The Indian Space Research Organisation (ISRO) on Sunday (Apr 1) announced that it has lost all contacts with its recently launched GSAT-6A satellite.
Here is all you need to know about ISRO’s GSAT-6A satellite:
1. On Mar 29, the Geosynchronous Satellite Launch Vehicle (GSLV-F08) successfully launched GSAT-6A Satellite from Sriharikota into Geosynchronous Transfer Orbit (GTO).
2. With a 6-meter antenna for more efficient ground communication, tt was to be India’s largest communications satellite yet.
3. ISRO built the GSAT-6A communication satellite to provide mobile communication services through multi beam coverage. For this, it is equipped with S and C band transponders.
4. In its oval shaped GTO, GSAT-6A was orbiting the Earth with a perigee (nearest point to Earth) of 169.4 km and an apogee (farthest point to Earth) of 36,692.5 km with an orbital inclination of 20.64 deg with respect to the equator.
5. On Mar 30, the ISRO confirmed that the first orbit raising operation of GSAT-6A satellite has been successfully carried out by Liquid Apogee Motor (LAM) Engine firing for 2188 sec from 09:22hr IST.
6. The second orbit raising operation of GSAT-6A satellite was successfully carried out by LAM Engine firing for about 53 minutes on March 31 in the morning.
7. After the successful long duration firings, when the satellite was on course to normal operating configuration for the third and the final firing, scheduled for April 1, communication from the satellite was lost.
8. The ISRO said efforts are underway to establish the link with the satellite.
9. The 2140-kg communication satellite was put on the orbit with a mission life of about 10 years.
10. It was the first mission of ISRO’s new chairman K Sivan after he assumed charge of the space agency in January.
