On Wednesday, India’s latest communication satellite GSAT-31 was successfully launched from French Guiana this morning, making it the third successful mission by Indian Space Research Organisation (ISRO) this year.
The GSAT-31 is a “high power” communication satellite with Ku-band. The weight of GSAT-31 is 2535 kg.
The satellite derives its heritage from ISROs earlier INSAT/GSAT satellite series, the space agency said, adding that it will provide communication services to Indian mainland and islands.
GSAT-31 is the country’s 40th communication satellite which is configured on ISRO’s enhanced ‘I-2K Bus’, utilising the maximum “bus capabilities” of this type.
This satellite will augment the Ku-band transponder capacity in Geostationary Orbit, ISRO said.
With a mission life of around 15 years, GSAT-31 will be used for supporting VSAT networks, Television uplinks, Digital Satellite News Gathering, DTH-television services, cellular backhaul connectivity and many such applications.
It will also provide wide beam coverage to facilitate communication over the large oceanic region, comprising large parts of Arabian Sea, Bay of Bengal and the Indian Ocean, using a wide band transponder.
According to ISRO, two Ku-band beacon down link signals are transmitted by the satellite for ground tracking purpose.
ISRO chairman K. Sivan said that “GSAT-31 has a unique configuration of providing flexible frequency segments and flexible coverage.”
The ISRO chairman added in a release that “GSAT-31 will provide DTH Television Services, connectivity to VSATs for ATM, Stock-exchange, Digital Satellite News Gathering (DSNG) and e-governance applications. The satellite will also be used for bulk data transfer for a host of emerging telecommunication applications.”
GSAT-30 is another geostationary satellite to be lofted soon by Arianespace. Since the launch of India’s APPLE experimental satellite on Ariane Flight L03 in 1981, Arianespace has orbited 23 satellites and signed 24 launch contracts with the Indian space agency, the European launch services provider said.
The next ISRO geostationary satellite to be launched by Arianespace will be GSAT-30.
