ISRO has lost communication with India's most powerful communication satellite, GSAT-6A which was launched just about 2 days ago on Thursday. ISRO said that it is trying to re-establish link but sources attributed a power system failure. ISRO is yet to officially confirm a power failure.
"The second orbit raising operation of GSAT-6A satellite has been successfully carried out by liquid apogee motor (LAM) Engine firing for about 53 minutes on March 31, 2018 in the morning. 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, 2018, communication from the satellite was lost. Efforts are underway to establish the link with the satellite," ISRO said.
The second orbit raising manoeuvre was successful but ISRO received data from the satellite for just about 4 minutes' after the second orbit raising operation. The satellite was supposed to be fired to the third and final orbit manoeuvre before it lost communication.
GSAT-6A is a high power S-band communication satellite configured around I-2K bus. The mission life of spacecraft planned is about 10 years and it would be able to send and receive signals from handheld devices. The cost of the 2-tonne satellite is estimated to be rupees 270 crores. The satellite's capacity can also be used for strategic and social applications.
