EDUSAT Applications Take off The
utilisation of ISROs first thematic satellite, EDUSAT, took
off with the inauguration of EDUSAT based Primary Education Project
in Chamarajanagar District of Karnataka on March 7, 2005. The Chief
Minister of Karnataka, Mr Dharam Singh inaugurated the project at
ISRO Telemetry, Tracking and Command Network, Bangalore.
Under
the project, taken up by ISRO under EDUSAT distance education programme
jointly with the Karnataka State Government, 885 satellite receive
terminals have been set up predominantly in tribal areas Chamarajanagar
(289), Gundlupet (203), Yelandur (69), Kollegal (114), Kannur (194)
and H D Kote (14). This forms part of the Sarva Shiksha Abhiyan being
implemented by the Department of State Educational Research and Training
(DSERT). These Ku-band satellite receive terminals are intended for
programmes that supplement curriculum based teaching in the schools
and will be synchronised with the school time-table for covering the
syllabus. DSERT
has already produced 100 programmes on identified topics, which are
highly focused hot spots to improve the quality of education for the
students in remote tribal areas. Another 100 programmes are under
production. The programmes are produced in simple local language with
a good content of high quality animation to make the students understand
the basics in science, mathematics and languages. The local teacher
at each location will also act as the facilitator in helping the children
to understand the subjects and answer their questions. Each of the 885 Direct Receive Satellite terminals consists of a 1.2 m diameter Ku-band dish antenna, a set-top box and a 29 colour TV monitor to receive the programme. Each of these terminals is also provided a battery pack, which is charged by a solar panel to provide uninterrupted power supply for reception at least for a period of 2 to 4 hours. The system is housed in a specially designed, aesthetically appealing cabinet. The local custodian can easily operate the system. To avoid misuse of the terminals,TV is tuned to receive only EDUSAT based programme. The complete terminal including the solar panel-battery power supply costs about one lakh rupees. While ISRO is funding the cost of these terminals, DSERT produces the contents and local people maintain the sets. As the programme proceeds in Chamarajanagar district, periodic evaluation will be undertaken to optimise the content and delivery system to replicate the programme in other backward and remote places. The Karnataka Government is already proposing to add another 200 terminals in other parts of the State. Apart
from the Chamarajanagar Primary Education Project, Visvesvariah Technological
University Network with 100 nodes has been transferred to EDUSAT.
EDUSAT, launched by Geosynchronous Satellite Launch Vehicle (GSLV-F01) on September 20, 2004, is Indias first thematic satellite dedicated exclusively for educational services. Parked at 74 Deg East Longitude in the 36,000 km high geosynchronous orbit, the satellite is specially configured to relay through audio-visual medium, employing multi-media multi-centric system, to create interactive classrooms. EDUSAT has multiple regional beams covering different parts of India five Ku-band transponders with spot beams covering northern, north-eastern, eastern, southern and western regions of the country, a Ku-band transponder with its footprint covering the Indian mainland region and six C-band transponders with their footprints covering the entire country. The
Hub for national beam has been established at Ahmedabad. The national
beam is planned to be used for: Regional
beams of EDUSAT are planned to be as follows: Thus, EDUSAT is expected to herald a new era in the educational sector by bridging the distances and allowing effective optimum sharing of scarce resources for teaching.
