GSAT-14 will affect tele-education and tele-medicine

The delay in launch of GSAT-14 due to leak in the UH25 fuel system of the liquid second stage during the pre-launch pressurisation phase on the vehicle will affect tele-education and tele-medicine sectors.

Both tele-education and tele-medicine needs a big boost in India due to lack of quality teachers and specialist doctors in the country. With bandwidth acting as a constraint, these two sectors will definitely be affected to a larger extent as we are still a long way to go with respect to large scale deployment of tele-education and tele-medicine.

Tele-education and tele-medicine are presently limited to pilot projects whether by state governments or central government and one is yet to see a large scale commercial deployment which can benefit a large audience. These applications will be helpful in the long run for improving human development index of India.

GSLV-D5 launch vehicle was planning to launch 1982 Kg GSAT-14, a communication satellite into Geosynchronous Transfer Orbit (GTO) as it had lot of transponders related to tele-education and tele-medicine based on extended C, Ku-band, Ka-band transponders.

The cuboid shaped GSAT-14 has a lift-off mass of 1982 kg and the dry mass of the satellite is 851 kg. It is based on ISRO’s 2 ton class platform (I-2K satellite bus). The two solar arrays (each with two panels) of GSAT-14 together generate about 2600 W  of power, while the light weight Lithium-Ion Batteries supply power during eclipse period.

GSAT-14 is the twenty third geostationary communication satellite of India built by ISRO. Four of GSAT-14’s predecessors were launched by GSLV during 2001, 2003, 2004 and 2007 respectively. After its commissioning, GSAT-14 will join the group of India’s nine operational geostationary satellites. The 12 transponders will help in performing new experiments related to tele-education and tele-medicine.

The six extended C-band transponders provide Indian mainland and island coverage with 36 dBW Edge Of Coverage-Effective Isotropic Radiated Power (EOC-EIRP). Six Ku-band transponders covering mainland India with 51.5 dBW EOC-EIRP and two Ka-band beacons operating at 20.2 GHz and 30.5 GHz to carry out attenuation studies.

ISRO needs to get its act fast and launch GSAT-14 so that the transponders can be put to good use for tele-medicine and tele-education.
