ISRO has come up with the concept of dedicated GRAMSAT satellites, keeping in mind the urgent need to eradicate illiteracy in the rural belt which is necessary for the all round development of the nation.
This Gramsat satellite is carrying six to eight high powered C-band transponders, which together with video compression techniques can disseminate regional and cultural specific audio-visual programmes of relevance in each of the regional languages through rebroadcast mode on an ordinary TV set.
The high power in C-band has enabled even remote area viewers outside the reach of the TV transmitters to receive programmers of their choice in a direct reception mode with a simple .dish antenna.
The salient features of GRAMSAT projects are:
i. Its communications networks are at the state level connecting the state capital to districts, blocks and enabling a reach to villages.
ii. It is also providing computer connectivity data broadcasting, TV- broadcasting facilities having applications like e- governance, development information, teleconferencing, helping disaster management.
iii. Providing rural-education broadcasting.
However, the Gramsat projects have an appropriate combination of following activities.
(i) Interactive training at district and block levels employing suitable configuration
(ii) Broadcasting services for rural development
(iii) Computer interconnectivity and data exchange services
(iv) Tele-health and tele-medicine services.
