the twelfth in the Indian Remote Sensing (IRS) satellite series, is an advanced
remote sensing satellite capable of providing scene-specific spot imagery. It
will join the other six IRS satellites which are in service -- IRS-1C, IRS-1D,
OCEANSAT-1, Technology Experimental Satellite (TES), RESOURCESAT-1 and
CARTOSAT-1. It carries a Panchromatic camera (PAN) to provide imageries with a
spatial resolution of better than one metre and a swath of 9.6 km. The
satellite can be steered up to 45 deg along as well as across the track. The
data from the satellite will be used for cartographic applications at cadastral
level, urban and rural infrastructure development and management, as well as
applications in Land Information System (LIS) and Geographical Information
Soon after its separation from the DLA, the two solar arrays of
CARTOSAT-2 were automatically deployed to generate the electrical power for the
satellite. The satellite health is being continuously monitored from the
Spacecraft Control Centre of ISTRAC at Bangalore with the help of its network
of stations at Bangalore, Lucknow, Mauritius, Bearslake in Russia, Biak in
Indonesia, as well as support from Svalbard ground station in Sweden for the
initial phase of the CARTOSAT-2 mission. Further operations on the satellite
like orbit trimming, checking out the various subsystems and, finally,
switching on the cameras will be carried out in the coming days.
With ISRO Satellite Centre (ISAC), Bangalore, as the lead
Centre, CARTOSAT-2 was realised with major contributions from Space
Applications Centre (SAC), Ahmedabad, LPSC at Bangalore, and IISU,
Thiruvananthapuram. ISTRAC is responsible for initial and in-orbit operation of
CARTOSAT-2. The National Remote Sensing Agency (NRSA), Hyderabad receives and
processes the data from CARTOSAT-2.
capsule Recovery Experiment (SRE-1): Space capsule Recovery Experiment
(SRE-1), developed by ISRO's VSSC and ISAC, is a 550 kg capsule, intended
to demonstrate the technology of an orbiting platform for performing
experiments in microgravity conditions. After the completion of the
experiments, the capsule will de-orbited after a few days and recovered. SRE-1
mission will provide valuable experience in such important fields like
navigation, guidance and control during the re-entry phase, hypersonic
aero-thermodynamics facilitating the development of reusable thermal protection
system (TPS), recovery through deceleration and floatation besides acquisition
of basic technology for reusable launch vehicles.
SRE-1 carries two experiments, an Isothermal Heating Furnace
[IHF] and a Biomimetic (Biomineralisation of Inorganic materials) experiment.
IHF will be operated to perform metallurgical experiments while Biomimetic
experiment will be operated to perform Biomimetic synthesis. SRE-1 comprises
aero-thermo structure, spacecraft platform, deceleration and floatation system
besides the micro-gravity payloads. It has a sphere-cone-flare configuration
with a spherical nose of about 0.5 m radius, base diameter of 2 m and 1.6 m
height. The capsule is made of mild steel. The parachute, pyro devices,
avionics packages of triggering unit and sequencer, telemetry and tracking
system and sensors for measurement of system performance parameters are placed
inside SRE capsule.
Two days before de-orbiting, SRE-1 will be placed in a
Repetitive Elliptical Orbit. Subsequently, it will be reoriented and deboost
rocket is fired to make it reenter the earth's atmosphere. Close loop
guidance system is employed during deboost and coasting phases leading to its
recovery. On re-entry, after initial aerodynamic braking, a parachute system
will reduce the touch down velocity. SRE-1 will splashdown in the Bay of
Bengal, east of Sriharikota coast. A floatation system will keep SRE afloat and
enables its recovery.
SRE-1 is being tracked and monitored by ground stations at
Bangalore, Lucknow, Mauritius, Biak in Indonesia, Bearslake in Russia,
Saskatoon in Canada and Svalbard in Sweden/Transo in Norway.
and PEHUENSAT-1: LAPAN-TUBSAT and PEHUENSAT-1 were launched under
commercial agreements. LAPAN-TUBSAT is a cooperative venture between Indonesian
Space Agency, LAPAN and Technical University of Berlin. It is an earth
observation satellite besides a technical demonstrator in control systems. The
56 kg LAPAN-TUBSAT carries two Charge Coupled Device (CCD) cameras with ground
resolutions of 5 m and 200 m respectively. It also carries an experiment for
message store and forward system.
is a 6 kg Argentinean nano-satellite meant to serve educational, technological
and scientific fields. PEHUENSAT-1, developed by University of Comahue of
Argentina, AMSAT (Amateur Satellite Association of Argentina) and Argentina
Association for Space Technology, is intended to provide an experiment platform
to perform amateur radio experiments between colleges and universities of
With its ninth consecutively successful launch today, PSLV has
once again proved its reliability and versatility to orbit multiple satellites
and launch satellites in different types of orbit. In today's launch,
several improvements to the vehicle and the Dual Launch Adopter have been
proved in flight.
