Uses of GSAT-31

It will be used for supporting VSAT networks, Television uplinks, Digital Satellite News Gathering, DTH-television services, cellular backhaul connectivity and many such applications, as it provides wide beam coverage to facilitate communication over large oceanic region, using a wide band transponder. 

GSAT-30 will be the next geostationary satellite to be lofted 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.

“Arianespace is honored ISRO has entrusted Ariane 5 for two launches back-to-back, with the last Ariane 5 of 2018 launching GSAT-11, and today the first one of the year 2019, which orbited GSAT-31,” said Arianespace CEO Stephane Israel.
