VISION
In my younger days, I had the good fortune of working closely
with the space pioneer Dr. Vikram Sarabhai. I was always struck
by the professional and personal rapport between JRD Tata and
Vikram Sarabhai. About Vikram, JRD fondly mentioned, "Few
men that I have known call for more admiration and affection than
Vikram Sarabhai"
While JRD was a pioneer in aviation, Vikram was a pioneer in
space. Vikram's vision was to make India second to none in the
use of space to leapfrog the process of development. The uniqueness
of this vision was that he saw new opportunities in space for
a developing country like India, barely within three years of
the launch of the first Sputnik. And this was in contrast to the
common perception that the spectacular space feats of the early
era were nothing more than an extension of the cold war rivalry.
More explicitly, in the vantage point of space, he perceived possible
solutions to issues of national development, particularly those
relating to communication, broadcasting of educational and other
developmental programmes, timely and precise information about
natural resources, meteorological observations and natural disaster
management. His intuitive mind saw that space is a community resource,
having outreach to all and capable of serving without distinction
between rich and the poor and transcending barriers of knowledge,
literacy and any form of social or geographical imbalance.
It is interesting to note at this juncture, that these kinds of
remote and not so obvious relationships between developments in
science and technology elsewhere with totally different objectives
and their pragmatic relevance to deal with down to earth problems
in the context of a developing country like ours, is something
that we need to be continuously seized with.
BEGINNINGS OF A CULTURE - TOWARDS A
STRATEGY:
The space activities in India had modest beginnings. A pioneering
step was, initiating a sounding rocket program in the Southern
tip of India to enable scientific investigations of the unique
upper atmospheric and ionospheric phenomena above the geomagnetic
equator.
While the scientific purpose was the immediate aim, such a step
was crucial in developing the nucleus of a new culture in which
large group of persons in diverse activities learn to work together
for the accomplishment of a single objective. The real social
and economic fruits of technology can be realized only by those
who apply them through understanding.
It was also understood that engaging in advanced fields of research,
inevitably leads to establishment of collaborative relationships
at international level, an ability to deal with peers and a capability
to establish mutuality that can sustain such relationships; even
when the flow of know how is in one direction to start with. Establishment
of a Space Science and Technology Centre in the vicinity of the
Thumba Equatorial Rocket Launching Station, for developing expertise
in aerospace engineering, manufacture of atmospheric sounding
rockets and a modest satellite launcher was an important step
in that direction. The aim was to produce men and women who acquire
the capability to do front ranking research. Once such human resources
were created, organizing task oriented projects for tackling nation's
practical problems became possible.
STRATEGY TO SYSTEMS
The Indian Space programme evolved through three major phases.
The first phase related to initiation of activities with the objective
of proof-of-concept evaluation, followed by the experimental phase
of realizing end-to-end capability demonstration and leading finally
to the operational phase for providing regular services.
In the initiation phase, one of the primary tasks was evaluation
of the efficacy of space systems as either alternative to conventional
terrestrial systems, or to look at them as complementary or supplementary
to the conventional approaches, particularly in the area of resource
management. The pioneering Satellite Instructional Television
Experiment (SITE) was such a step to evaluate the efficacy of
the satellite broadcasting system with a vast outreach to provide
developmental communications and literacy. SITE was a unique sociological
experiment of its kind anywhere in the world, involving 2400 villages
spread over six states of the country, covering nearly 200,000
people and it used the American ATS-F satellite. Another interesting
initiative was the Satellite Telephony Experimental Project (STEP),
using the Franco-German Symphony Satellite for evaluation of the
overall technical interfaces between space and ground systems
towards improving the communication capabilities. In the case
of remote sensing, for earth resources survey, the first American
satellite LANDSAT was used to acquire imageries of the Indian
landmass towards assessing the ability to quantify the various
natural resources and in some cases their dynamics.
In all these studies relating to the initiation
phase, use of foreign space systems, configuring the ground system
to suit the national needs and conditions, and working closely
with potential user community, were the essence of the related
efforts. This phase also witnessed the development of the first
satellite launch vehicle SLV-3, with a capability of orbiting
40 Kg class of satellites to low earth orbit.
In the second phase, i.e. experimental phase, a major exercise
was undertaken to create an end-to-end capability in the design,
development and in-orbit management of space systems, together
with the associated ground systems needed for the users. These
were systems with limited capability, realized within stringent
cost and time controls. In the case of remote sensing, the experimental
satellites Bhaskara-1 and Bhaskara-2 were the pioneering steps
in this direction. The Bhaskara mission, even with 1 km resolution,
enabled developing the capability to image from space, transmitting
and processing the image information on the ground, disseminating
the data products to the users and getting their response. The
Ariane Passenger Payload Experiment (APPLE), provided the unique
opportunity to design and develop a 3-axis stabilized communication
satellite with all the relevant technologies, but with the limited
capability of two transponders. Besides building, deploying and
in orbit management of such a satellite, a number of interesting
communication and broadcasting experiments were carried out with
APPLE as the forerunner of future operational communication satellites.
In the operational phase, major space infrastructures have been
created over the last two decades. Such infrastructure broadly
fall under two classes; one for communications, broadcasting and
meteorology, through a multi-purpose satellite system (INSAT)
and second, the space based remote sensing infrastructure, the
Indian Remote Sensing satellite series (IRS). Currently the INSAT
system consists of six satellites with a total capacity of 80
transponders, providing services for telecommunication and television
broadcasting. The broadcasting capabilities of these satellites
are not only used for regular entertainment, but also for distance
education, and developmental communications. More recently, these
capabilities are being used for newer areas of applications like
telemedicine and e-Governance. The communication capability of
the INSAT system has significantly improved the quality and support
of high-density traffic between metropolitan areas. At the same
time, it has extended the outreach to less accessible areas like
Northeast and the islands. These satellite communications have
also ushered in a new era of business communications among closed
user groups, particularly using VSATs. The meteorological system
of the INSAT is unique for this region, enabling vital information
for weather and severe storm warning.
On the remote sensing side, creation of an operational space
based Earth Observation System has received a major thrust recognizing
the crucial need for timely, accurate and precise information
on natural resources. Based on the experience of the experimental
satellites, the BHASKARAs, and taking into account the unique
nature of the Indian requirements such as in agriculture, the
first of the operational Indian Remote Sensing satellite was designed
and developed over a time frame of 1982-88. The IRS-1A launched
in 1988 compared favourably in its performance with the then contemporary
satellites elsewhere. Within three years, an on-orbit spare IRS-1B,
was also orbited. Parallely, the second generation IRS system
has been developed with improved capabilities of observation and
providing best resolution of 5 meter compared to the 35-meter
capabilities of the first generation. The unique complement of
sensors onboard IRS-1C/1D makes this as one of the most versatile
civilian satellites available for earth observations anywhere.
Parallely, the Earth Observation Satellite infrastructure was
further augmented through orbiting two more satellites primarily
for ocean observations. The second in this series, IRS-P4, carries
sensors both for physical and biological oceanographic studies.
Thus the currently available Indian constellation for land and
ocean observations represents perhaps a unique constellation of
its kind anywhere, for earth observation particularly from the
point of view of resource information generation and management.
It is thus to be noted that the current operational systems,
both INSAT and IRS, have capabilities at contemporary levels and
could provide services which are comparable to the best anywhere
in the world.
Even though, the third phase has resulted in setting up operational
space infrastructure for regular services, the quest for newer
applications and higher levels of performance continues. In this
context, the phases of initiation and experimentation will continue
to be relevant. Some of the newly emerging areas are navigation,
geographical positioning, high-resolution imaging, microwave remote
sensing, mobile communications and Direct to Home broadcasting.
Newer dimension in bringing above areas into operational status
is to address the issues related to the use of global systems,
create or share regional systems, or set up national systems.
Towards achieving the operational status as elaborated earlier,
certain strategies were to be adopted and pragmatic decisions
to be made, down the way, at different points in the programme.
Let me give a few examples. Encouraged by the lessons of the SITE
experiment and based on the potentialities of a space-based communication
and broadcasting system for developmental needs of the country,
it was decided to go for a space-based communication and broadcasting
system. Taking into account, the time frame for the design and
development of an operational INSAT satellite and noting the urgency
to initiate the services in this area, it was decided to go for
creating this infrastructure by a bought out option for the first
generation INSAT systems, even as we embarked on the design and
development of the second generation systems. The four satellites
of the first generation were thus procured, launched and operated
for providing space based communication and broadcasting services
for the national needs in the first instance. On the other hand,
the strategy adopted was different in the case of earth observations.
Although it was decided to go ahead with the use of then existing
foreign satellites for developing the remote sensing applications
in the country, the special requirements of earth observations,
peculiar to our country, called for an indigenous design and development
strategy for the realisation of the first generation operational
remote sensing satellite systems.
Another example relevant to the present discussion is about the
decision, in the early phase itself, to de-couple the time frame
for the development of the launch vehicles and their operational
support to the satellite launches. Considering the complexities
of launch vehicle development and the need to have several validation
steps including actual flights with the attendant longer time
frame for the realisation of such capabilities, it was consciously
decided, in the programme to seek launch support services for
the operational satellites with outside agencies. Such a strategy
enabled on the one hand timely establishment of space system services
for national development and on the other hand provided specific
inputs for defining the capability for launch systems for these
classes of satellites. In this process, the operational capability
for launch of IRS class of satellites has now been realised with
Polar Satellite Launch Vehicle (PSLV) which can put one tonne
class of satellites into polar orbit from Sriharikota and thus
compatible with the present generation of IRS. The development
of Geosynchronous Satellite Launch Vehicle (GSLV) has matured
with the successful first test flight of this vehicle early this
year. Operationalisation of GSLV in the near future will result
in a similar capability for launching INSAT class of satellites.
One important message that emerges from the above discussions
is that in introducing high technology system for objectives relating
to developmental and other innovative service, judicious decisions
need to be made involving careful assessment and evaluation of
most suitable systems, exercise of buy or build options and planned
development of the capabilities well dovetailed to the user needs
leading to the timely introduction of such systems duly factoring
the consideration of self-reliance in a pragmatic way.
SYSTEMS TO INSTITUTIONS:
As observed earlier, right from the inception stage, planning
of the space systems has been clearly dovetailed to the ultimate
user needs. Experience from earlier experiments involving broadcasting,
communication and remote sensing, and dealing with the user communities,
provided the inputs for the creation of appropriate formal institutional
frameworks. These in turn became the starting point for the definition
of the scope for the space systems. In the case of remote sensing,
the institutional framework involved setting up of the Preparatory
Committee of the National Natural Resources Management System
(NNRMS), which later transformed into Planning Committee of NNRMS.
This committee, which at the overall level provides the directions
for the creation of remote sensing capabilities for the country,
consists of Secretaries of the line departments of the Government
of India dealing with natural resources and headed by a Member
of Planning Commission. Such a structure enables, on the one hand,
involvement of major user communities to address issues of ensuring
the use of such systems in their own areas of thematic applications
and on the other hand to facilitate incorporating this new and
powerful technique into the related conventional approaches. Similarly
the INSAT Coordination Committee, with the Secretaries of the
user departments, namely Information and Broadcasting, Communication,
Information Technology and Science and Technology with the participation
of the Space Department, is the apex body to address the development
of space communication and broadcasting and planning of their
utilisation for the TV networks as well as for telecommunications.
The broadcasting capability further has been used through the
same mechanism to promote distant education, developmental communication
and other socially relevant developmental activities. In the context
of Space Science, the Advisory Committee On Space Sciences consisting
of some of the leading space scientists in the country provides
directions for space science research. The three structures identified
above, are unique to our country with no parallel, anywhere else
in the world.
An important outcome of the creation of such institutional framework
is that every time a satellite is sent to space, there is no question
of looking for its users. Being user driven also meant the beginning
of a culture of accountability and transparency. Further, these
institutional mechanisms are unique in recognising the socio-
economic imperatives at the grass root level and facilitating
integration of the space capabilities into the existing conventional
systems.
Even as these institutional frameworks have worked effectively
in managing the Indian Space Programme, we have not been oblivious
to the changing situations in the overall context of the country,
particularly the impact of new developments of globalisation,
liberalisation and economic integration. Against this backdrop,
constant review of the existing legal and policy framework has
also been receiving the attention. A recent example is the satellite
communication policy that enables private investments into satellites
for satellite ownership and registration within the country. This
is a major step in bringing private sector into the ownership
and operation of satellites. Similarly, in the area of remote
sensing, policy for the dissemination of high-resolution imageries
has been announced. This is expected to enhance the use of remote
sensing in civilian activities.
As space activities are expanding and creating new opportunities
for a variety of segments like NGOs , industries and service organizations,
ISRO is diversifying the institutional framework for space activities
as evident from the policy initiatives just mentioned. ISRO has
helped creation of an informal framework in which NGOs and service
providers in private sector have collaborated constructively in
defining our plans and in promoting expanded use of space. This
is in addition to the already increasing role of private entrepreneurs
in providing value added service in thematic resource areas. Particularly
note-worthy has been the association of non-governmental agencies
in areas such as watershed development and telemedicine.
SYSTEMS AND TECHNOLOGY INNOVATIONS:
Building technological competence is a key factor for the success
of space programs. Starting from basic developments, ISRO has
achieved a level of technology, which is world class. The Indian
Remote Sensing program is an excellent example of achieving this
level of world leadership. Innovative approach is key to such
a development. With the inputs from the initiation and experimental
phases as elaborated earlier, we were in a position to take the
next step, to achieve a quantum jump in terms of establishing
a National Earth Observation system for natural resources management.
In contrast to expensive, heavy spacecraft with complex moving
mechanisms adopted by the world for earth observations, the first
generation IRS was designed with many innovations. A pioneering,
but risky, step of using solid-state detector arrays ensured simplified
designs, besides triggering development of novel optical systems
and an original approach to low weight spacecraft. This gave better-cost
efficiency, improved turn around time for manufacture, a high
degree of reliability, yet a performance comparable to best systems
in the world. This choice of solid-state detectors also offered
better growth potential - and in fact became a world trend.
The very constraints that India faced in terms of overall launch
capability were also turned to advantage by innovation to realize
lightweight and compact state of art satellites. In the very next
generation (namely IRS-1C and 1D satellites) further innovations
have enabled new capabilities that outperformed contemporary systems.
A unique combination of sensors ranging from high resolution cameras
to multi-spectral and wide angle camera systems were incorporated
in the satellite - making them the best systems in commercial
domain. In view of such capabilities, they have become part of
global source of remote sensing data, sharing about 20% of the
world market at the present juncture.
Influence of external environment is a powerful triggering factor
on innovations. The total embargo on technologies related to space
launch systems have demanded development of technology - starting
from scratch. Such a constraint has brought the best out of our
human resources, particularly through teamwork - taking technology
to the highest level of performance. The solid propulsion technology,
developed by ISRO, is one of the examples where such excellence
is seen. Solid propellant based first stage used in PSLV or GSLV
is among the top four in the world. The use of Fuel binder Hydroxyl
Terminated Poly Butadine (HTPB) was a pioneering step for solid
rocket motors resulting from such innovations, in which industry
was also a partner. This also became a trendsetter in the world
of solid rocket propulsion.
Even, with the above type of emphasis on totally indigenous routes
to technology realization, ISRO at no point of time was averse
to adopt technologies available elsewhere, in case there is a
distinct advantage for exercising such an option in terms of timeframe
and cost. The ability to continuously upgrade and update the technology
through adoption and absorption of technologies from outside,
suitably tuning them to our specific needs and subsequently improvising
and improving them to take it to higher levels of efficiency standards
and performance, has also been a strategy which has been adopted
in many cases.
Lastly, total systemic technology, acquired from abroad has also
been used in the ISRO programmes with subsequent modifications
and resultant improvements. It should be noted that both the second
and third approaches, do call for certain basic level of competence
and capability within the organization, as technology absorption
cannot take place without an indigenous competence base. The attendant
innovation introduced to such technology further upgrades it.
In the absence of such indigenous competence base, and lack of
innovation, there is a risk of perpetual dependence on the original
source.
SYSTEMS AND APPLICATION INNOVATIONS:
The raison d'etre of institutions created for space is the delivery
of service to society through applications. Significantly, applications
of space are distinguished by their ability to shrink time and
distance - the hallmark of innovations from space.
Space is a bridge that can connect the most backward and isolated
areas with the most developed ones in a rapid way.
The urban medical centers for example can be linked to health
centers in remote villages and small towns, extending the services
of specialists who are available only in cities. Vital information
needed for development in rural areas can reach the needy farmers
or extension workers in a timely way from experts located in a
district or state headquarters. There are areas where conventional
methods or tools are too cumbersome to employ to get results in
a timely fashion, as in cases of conducting nationwide surveys
of forest inventories or generating a terrain map for the whole
country. Use of space technology is vital in these cases. However,
there are many other areas where space inputs can be combined
with the traditional methods in an innovative way so that there
is visible improvement in the result. Success rate in drilling
wells was doubled when space information was integrated into the
conventional data. Where as conventional methods demand step-by-step
process to reach the last mile, the space technology can bypass
that route. A significant advantage of space again is its flexibility
for integration of several newly emerging technologies and such
a convergence can be seen in cases of space based internet gateway
services, digital video broadcasting, mobile communications and
disaster management support.
SPACE COMMUNICATIONS:
Although taken for granted now, the communications via space
had been the source of extraordinary innovations in applications.
The foremost from INSAT system was phenomenal expansion of television
coverage in India. Television was barely covering eight urban
centers when the worlds' largest sociological experiment SITE
beamed television programs to 2400 villages in 1975. Soon after
the establishment of INSAT in early 1980's, the television has
grown into a nationwide phenomenon and now it can provide access
to 87% of population with over 1000 transmitters in INSAT network.
Besides influencing social and cultural landscape of India, television
primes substantial economic activities. Each satellite communication
transponder, whose typical annual lease charges are about Rs.5
crores, triggers average advertisement revenue of Rs.50 crores.
In case of VSAT service providers, typical value additions range
from 2 to 3 times lease charges. The satellite TV and VSAT services
present a growing market opportunity in India. The advent of new
technologies for digital video broadcasting and advances in satellite
technologies which offers greater flexibility in allocation of
space resources in tune with demands will be exploited in future.
The national demand for transponders is expected to grow from
the present level of 80 - 100 numbers to about 250 in various
frequency bands in the next five years.
Indian entrepreneurs will have to venture into production, ownership
and operations of satellites for communications. Such a role for
industries will be the integral part of maintaining national capability
in this vital area of infrastructure that covers spectrum of services
to economic, social and strategic sectors of the country.
No future revolution is going to take place without the role
of knowledge. Even in contemporary industrial evolution, knowledge
is a major player. If we have to advance nationally and also wish
to play a meaningful role in the comity of nations, imperative
of rapidly spreading literacy, education and skills cannot be
over emphasized. The most important resource to achieve this goal
is the teacher or trainer. In past, there has been tremendous
effort to enhance access of rural population and the urban poor
to schools. Number of primary schools registered a three-fold
increase from 1950-51 to 1998-99 to a level of 6.27 lakhs. The
upper primary schools too saw a more dramatic growth and reached
a number of 1.9 lakhs in 1998-99. However, if we look at the student
to teacher ratio, the situation is not encouraging. There is on
the average 58 students for each teacher at primary level and
corresponding number is 32 students at upper primary level. In
real terms, the growth in the number of teachers has fallen steadily
over time from 5.6% in 1952 to 4.6% in 1960's and 2.7% in 1970's.
Between 1984-85 and 1989-90, the growth rate dropped to 1.6%.
All these statistics indicate the shortage of teachers and more
importantly the need for an effective way to maintain quality.
The spatial asymmetry of development and the scarcity in availability
of human resources are key issues and therefore the relevance
of distance education is high in our context. Similar arguments
apply for upgrading of skills in a number of areas including professional,
continuing and higher education.
Extensive experience gained through the use of INSAT in several
states and conduct of innovative experiments such as Jhabua Development
Communications Project have increased the awareness, demand and
urgency for evolving a robust national system for tele activities
such as distance education, telemedicine and a wide range of training
and developmental communications. Main goal here is to energise
an innovative social process that will enhance human resources
quality rapidly. The strategy is to elevate the general level
of performance and to prevent pulling down the high performers
to mediocre levels. The GRAMSAT network conceived by ISRO is meant
to promote above goals and is directed to serve underdeveloped
locations, through innovative use of satellite system, addressing
vital social needs. This network aims to bring in synergy of a
wide variety of organisational mechanisms - the voluntary bodies,
government agencies, entrepreneurs, service industry and academic
institutions.
CONTRIBUTION FOR METEOROLOGY AND CLIMATE
STUDIES:
Advent of INSAT system provided the synoptic viewing capability
for weather related phenomena over India and its neighborhoods.
As weather forecasting is a complex science which relies on extensive
data collected both from ground and space platforms and use of
sophisticated computer models, INSAT's role in imaging the weather
systems of the region and collection of data from a number of
unattended platforms and dissemination of data as well as information
to various processing centers is significant. Globally, experience
has shown that improvement in weather forecast depends on several
factors and 15-20% can be attributable to the contributions from
satellites. However, in case of severe weather systems like cyclones,
this contribution could be as high as 60%. The most important
application, which was developed by the India Meteorological Department,
using the imaging capability of INSAT, is the tracking of cyclones
and timely dissemination of warning information to vulnerable
sections of population and concerned authorities. INSAT's meteorological
observation capability is also of considerable interest to global
community and this has recently become an instrument for furthering
international cooperation. Future Indian weather satellites will
continue to play a prominent role in improving accuracy and horizon
of weather forecasts, which are important for agricultural operations
such as sowing, irrigation and pest control and for several other
sectors of economy. International community is seeking India's
active role in promoting global cooperation in space-based meteorology
and its applications. Megha Tropiques mission, which is being
jointly planned by ISRO and the French National Space Agency (CNES)
is a shining example of a unique mission for serving global scientific
community.
NATURAL RESOURCES MANAGEMENT:
Impact from Indian Remote Sensing Satellites arises from two
diverse functions. In the first place, they enable overall survey
of natural resources so that the information they provide becomes
the basis for strategic planning and policy formulation. Secondly
when these strategies are implemented - the satellites fulfill
the need for timely monitoring of the results. Space based data
enables efficient understanding of interrelationships among various
resources and the impact of human intervention. Such a capability
is the key to evolve strategies for sustainable development and
use of natural resources.
In what follows we provide a few examples of the role of satellites
in monitoring and inventory of natural resources.
Agriculture :
Proper estimate of agricultural yields in advance have tremendous
impact on our economy as well as social life. Data from IRS have
been regularly utilized for assessing the areas under various
agricultural crops in various states and also for prediction of
their yields about a month in advance of harvest, to the level
of accuracies demanded by the Bureau of Economics and Statistics
(90% accuracy/90% confidence level). As a sequel to this experience,
an improved model for a National System for Forecasting Agricultural
output using Space, Agro-meteorology and Land based observations
(FASAL) is being instituted by the Ministry of Agriculture.
In past, data from Indian remote sensing satellites have also
been effectively used (i) for monitoring irrigation commands (for
which the country has invested Rs.200, 000 crores, at 96-97 prices,
in major and medium irrigation projects) (ii) for faster reclamation
of water logged and salt affected lands and (iii) for developing
strategies for micro watershed management which is key to economic
development of rain-fed rural areas, resulting in visible improvement
in productivity wherever implemented.
Space will continue to be a valuable tool to face the challenges
of current times and of future in the field of agriculture, which
accounts for nearly 65% of nation's employment and 26% of GDP.
Its key challenges in terms of making it profitable for farmers,
diversifying it, promoting capital formation, value addition,
improving market access, sustaining and improving productivity,
all need a sound strategy for its implementation.
A vision for an innovative route of development in agriculture,
with the backdrop of WTO regime and ecological crises that threaten
to bring down productivity, could truly be derived from the convergence
of biotechnology with space and informatics. Precision agriculture
embodies such convergence. With a goal to achieve a quantum jump
in agricultural productivity and reduced cost of cultivation,
the precision agriculture plays catalytic role in order to achieve
a common ground based on convergence of space, bio - and information
technologies combined with diversified and resilient agricultural
systems. Model of precision agriculture has to be adopted to India
taking into account the predominance of fragmented land holdings,
heterogeneity of crops and livestock, and concepts of farm families
in our rural conditions.
While the ecological integrity of farming systems is an imperative
need, it is equally important to extend the access of information
and market to the small farmers. The precision agriculture model
for India while addressing these issues provides an innovative
route for sustainable agriculture in globalised and liberalised
economy.
At the core of this new emerging agricultural regime will be
the dynamic information services emanating from space-based systems,
which can provide strategies for cropping systems. These strategies
can also integrate objectives of sustaining productivity of land
and water resources, maximizing returns from them and also effectively
responding to external factors such as prices, which are influenced
by global markets. Such strategies could be implemented with farmers
participation facilitating 'aggregated farming' so that productivity
can still be enhanced overcoming the disadvantage of fragmented
land holdings.
In addition, for the country as a whole the synoptic vision of
a satellite combined with information services could provide necessary
inputs in planning for a cropping regime in different parcels
of agricultural land, taking due account of agro-climatic characteristics,
resource endowments and market conditions.
Targeting Drinking Water:
The ground water potential maps for entire country, prepared
during eighties, have been the major source of information that
contributed to the success of National Drinking Water Mission
(NDWM). Search for groundwater, particularly in areas with consolidated
and semi-consolidated rock formations, considered more difficult
from the point of view of exploration and recharge, is considerably
aided by the use of hydro-geomorphological maps prepared using
satellite data. These maps are extensively used for locating prospective
groundwater sites around problem habitation as a part of a ' scientific-source'
finding approach. This approach has raised success rate better
than 90% in most cases, compared to 45% success rate achieved
using conventional technique. Besides groundwater targeting, remote
sensing data also provides information about suitable sites for
recharge and thus enable the sustainable development of water
resources in the country.
Environment :
Since the early 1980s, when India began comprehending the impending
ecological catastrophe due to the ongoing deforestation and land
degradation, there has been some success in tackling these problems.
Remote sensing based Biennial Forest Mapping, Forest Working Plan
preparations, Catchment Area Treatment (CAT) plans, Encroachment
studies, Environment Impact Assessment (EIA) of Development Projects,
strengthened country's resolve in its march towards sustainable
development. India, which occupies 2.4% of world's land area,
has about 7% of global biodiversity. However, it also contains
two of the eighteen global hot spots of biodiversity. A joint
initiative taken up by Department of Bio-technology and Department
of Space on bio-diversity characterization at landscape level
is a true implementation of Gene to Ecosystem concept in biodiversity
conservation and prospecting. To start with, this initiative is
focused in the North East India - a bowl of plant diversity and
ecological hotspot. Besides implementing Bio-diversity convention
treaty, it helps in formulating the policy framework to ensure
environmentally sound sustainable development.
In the recent times, remote sensing has become an instrument for
judiciary to arrest the forest encroachment and enforce environment
sensitive legislations. For example, forest department of Maharastra
Government has found an innovative solution to tackle perennial
encroachment problems using multi-date remote sensing images.
Forest encroachment in Shirpur-Sangvi Ranges, Dhule, Maharastra
and Rajiv Gandhi National Park near Mumbai was delineated using
Indian remote sensing satellite data. Maharastra forest department
could win the court cases quoting the evidence of encroachment
generated from remote sensing data. Similarly, under the Enforcement
of Environmental (Protection) Act (1986), the Coastal Regulation
Zone prohibits any construction within 150 m from High Tide Line
(HTL) to preserve the mangroves. Remote sensing data enables monitoring
of changes in coastal zones to strengthen implementation of regulations
such as above.
DISASTER MANAGEMENT:
Innovative use of communication and meteorological
capability of INSAT system is an outstanding example of space
applications that helps in saving thousands of lives and livestock
in the coastal areas of India. Installation of the unique, unattended,
locale-specific Cyclone Warning and Dissemination System (CWDS)
consisting of more than 250 disaster-warning receivers in selected
cyclone-prone coastal areas have been providing advance warning
of the impending cyclone to the targeted villages, taking advantage
of the direct broadcast capacity of INSAT system. By virtue of
combining INSAT and IRS capabilities, warning, disaster assessment
and other services were extended during super cyclone of Orissa
in a rapid way that was unparalleled by other means. When this
state was affected by flood again this year, inundation maps were
generated with shortest turn around time, depicting the marooned
areas at regular intervals soon after floods in order to assist
relief operations. This information was disseminated to the user
community within hours through the Internet. ISRO's plan for the
country is to create a digital database covering all the areas
prone to disasters such as cyclone, floods, drought, landslides
and earthquakes. These databases will be so designed as to enable
rapid monitoring of natural disasters and to help in other disaster
management functions. In addition, rapid response to restore communications
will be a priority.
NATIONAL SPATIAL DATA
INFRASTRUCTURE (NSDI)
India is fast moving into being an information and knowledge society.
Emphasis is increasingly being placed on IT driven "transparent"
e-Governance. Recent initiatives by the Government, including
the IT Act, make it clear that within a few years an unprecedented
capability will exist for sharing of data along "electronic
superhighways". The nation has, over the past years, produced
a rich "base" of information through systematic topographic
surveys, geological surveys, soil surveys, cadastral surveys and
by use of remotely sensed images in a variety of thematic maps.
With the availability of precision, high-resolution satellite
images, use of tools and resources like GIS and GPS, the accuracy
and information content will be considerably enhanced for a variety
of uses. Access and availability of such information to the citizens,
society, private enterprise and government are important. As a
part of this vision, a National Spatial Data Infrastructure (NSDI)
is being evolved through a partnership approach among various
agencies who maintain data bases in the field of their specialty
following specified standards and protocols to facilitate, access,
integration and networking of data bases. The NSDI has been conceived
as national system that synergistically combines the resources
and infrastructure of various players, with the power of information
technology and enabling information support for decision making
in government, industry, academia and other organizations besides
serving the public needs.
With the overall leadership established in applications of remote
sensing data in the field of natural resources, ISRO's broader
vision for future is to develop a system for regular census of
nation's natural resources and generation of reports on "State
of the Country's Environment". Such census can identify natural
resource "hotspots", that are a cause for concern. This
in turn can lead to identification of environmentally sensitive
areas requiring urgent conservation/management action. National
Spatial Data Infrastructure is the mainstay to support the National
Resources Census activity.
Myriad are the innovation processes in applications of space.
The strong base created for continuous development of India's
space infrastructure will facilitate its expanded role for newer
and innovative applications, preserving our pre-eminent position
in this field.
OTHER DIMENSIONS:
Industrial Opportunities:
Indian Space Program derives substantial support from industry
and views that industry participation is an essential requirement
for the success and growth of the program. The program has adopted
a conscious policy of maximally utilizing the industrial capabilities
available in the country and to provide Indian industry with the
technical wherewithal through technology transfer and other support.
About 500 industries are participating in the space program in
a variety of roles. Currently more than 30% of the budget of the
Department of Space is spent in industries and in case of launch
vehicles like GSLV, industry contribution is as high as 70% of
product value. Another significant way in which the Indian industry
benefits from participation in space program is to imbibe the
culture of high technology products through the quality assurance
and reliability practices, multidisciplinary interfaces and other
spin offs. Of considerable interest to industries is the demands
triggered by the investments in space segment, for production,
supply and maintenance of ground equipment and also opportunities
for value added services. The demands for earth stations, the
user oriented equipment required for telecommunications, broadcasting,
meteorological data collection and transmission systems, information
processing, handling and networking equipment are two to three
fold as compared to space investments. They provide unique opportunities
for industries to service those markets. Over the last one decade,
there has been a significant progress in entrepreneurship for
providing value added services based on information generated
by satellite systems and those based on the use of space communications.
Strong capabilities of industry in such areas are justified by
fairly large market in India for such products and services, and
that expertise will also enable our industries to service markets
abroad, in other developing countries where needs are similar.
In execution of export orders bagged by Antrix Corporation of
Department of Space, Indian industry played an important role
in the manufacture, testing and assembly of specialized space
hardware which were exported to advanced countries like France
and USA. In the next five years the demand on space infrastructure
is likely to double and scope of participation for Indian industries
will also correspondingly increase. The Indian space program has
taken several policy initiatives to enhance the industries role
in terms of greater integration of space systems in industry,
development of consortia approach, policy for long term commitments
and partnership in commercial activities.
I am hopeful that in the near future, the Indian industry will
succeed in producing a total space system, not only for meeting
national needs but also for export to other countries. I assure
the representatives of Indian industries that ISRO will leave
no stone unturned to enable our industry to achieve a pre-eminent
position.
International Linkages:
International cooperation has always been an integral part of
the Indian space programme. Cooperation with USA in major programmes
such as SITE, with the then USSR for the launch of our early satellites
and with Europe for launch of APPLE gave impetus to early stages
of the programme. Over the years, as ISRO has matured in experience
and technological capabilities, the face of international cooperation
has changed from one of receiving assistance from developed countries,
to working with them as equal partners and also offering assistance
to developing countries. The success of the Indian remote sensing
satellites IRS 1C and ID offering the most sophisticated features
in the civilian realm till recently, and the PSLV providing opportunities
for commercial launches highlighted before the international community
that the Indian space programme had come of age. When ISRO flew
a German camera on its satellite and launched it with the PSLV,
it showed the world another possibility of working together with
India. The next launch of the PSLV saw two small satellites from
Germany and S. Korea as the first commercial payloads for the
PSLV. The forthcoming launch will have another German satellite
and one from Belgium. A major highlight of recent cooperative
endeavors is the development, launch and operation of the Indo-French
joint satellite mission, Megha Tropiques - dedicated to climate
research.
On the other side of the coin, great attention is paid for cooperating
with other developing countries and sharing with them the experience
and expertise we have gained. A major highlight of this approach
is the setting up of the Centre for Space Science and Technology
Education for the Asia Pacific (CSSTE-AP) in Dehra Dun offering
training programmes to the countries of this region.
On the commercial front, Antrix Corporation, in partnership with
Space Imaging of USA, has been successfully marketing data from
the IRS series of satellites through several ground stations set
up all over the world. Antrix also provides a single window to
the world for obtaining products and services from ISRO in different
aspects of space technology and applications.
ISLAND TO CONTINENT:
While we recognize that the Indian Space Programme is not the
panacea for all problems facing the country, there are many things
unique about the experience derived from doing space. Over the
years, the programme has enabled us to learn several things, which
are unique in their culture, content, approach and above all grassroot
relevance. Realisation of reliable space systems, whether it is
a launcher or a satellite, demands highest level of professionalism.
The requirements of reliable performance in the harshest of environments
put severe demands on the engineering and scientific skills in
terms of expertise, ingenuity and above all a high level of team
spirit. Further, even at the cost of repeating what I said earlier,
making the system relevant to the broader needs of the country's
development is a unique challenge for which original and innovative
institutional structures have to be thought of. The questions
related to level of technological developments in the broader
context of industrial base and manufacture are other issues that
had to be tackled suitably. Additionally, optimizing the resources
at the national level, for the conduct of space program, including
the involvement of R&D and academic institutions has been
an important factor. Creating internationally competitive systems,
which could provide global services, has been another facet of
this programme with its attendant challenges for addressing the
geo-political concerns, cost competitiveness and above all stringent
performance needs. Creating a viable space capability also means
the ability to establish new dimension of relationships with other
countries at the political level through the instrument of collaboration
and cooperation.
Above all, when one succeeds in a major space mission it signals
several other additional characteristics of a society:
a) that there can be a synergy between highly diverse systems
of engineering, technology, applications and development;
b) a success like that of GSLV further signifies that highly
complex technologies and engineering inputs can be synergised
for realisation of a system which performs exactly as set out
years earlier. This system capability in the broader context,
is also the need of the hour for realisation of several other
multidisciplinary projects;
c) for such an environment to succeed, it is extremely important
that there is a very well structured management system with high
level of communication between different levels and highest standards
of professional integrity and honesty;
d) In addition, when such a system is ultimately put to its intended
use, there is the additional important factor of user satisfaction.
This in turn implies complete transparency and accountability
for the entire effort.
Translating these and many other characteristics of a space endeavour
could considerably enhance, in our view, the quality of outcome
in similar efforts. Where as one has the satisfaction of seeing
this happening in many other areas in our country, much more needs
to be done. How do we do this? We need to identify and integrate
such islands of excellence into a holistic national development
strategy for optimal results; in other words from Island to Continent.
This is precisely what JRD had in mind when he wanted to make
the adventure of flying a continental endeavor. In a letter to
Mr. Ratan Tata who in 1965 was the President of the Jamshedpur
Co-operative Flying Club, JRD said,
"For many years I have wanted to see flying take its place
among the sporting and other extra-curricular activities of the
people of Jamshedpur, not only because of my own abiding love
for aviation, but also because of its character and nation-building
aspects. Although the flying of aircraft has evolved greatly from
the early pioneering days, it still requires most of the qualities
which go in the making of a good citizen of a country: skill,
discipline, self-reliance, physical fitness and coolness and courage
in emergencies".
