Significantly, This satellite is configured ISRO’s enhanced 1-2K bus, utilising the maximum bus capabilities of this type. The satellite, GSAT-31 would augment the ku-band transponder capacity in Geostationary orbit.

The ‘2,535-kg’ GSAT-31, satellite derives it’s heritage from ISRO’s earlier INSAT/GSAT satellite series. This is a versatile satellite with a unique configuration providing flexible frequency segment and flexible coverage. The satellite provides Indian mainland and Island coverage.

Moreover, It will provide continuity services on some of the in-orbit satellites. According to ISRO, GSAT-31, with a mission life of 15 years, will be used for supporting VSAT networks, television uplinks, digital satellite news gathering (DSNG), DTH television services, cellular back haul connectivity and many such related applications..

The satellite, provides a wide beam coverage to facilitate communication over large oceanic region comprising large part of Arabian Sea, Bay of Bengal and Indian Ocean using a wide band transponder.

However, it opened its 2019 mission activity by successfully orbiting a pair of telecommunications spacecraft – Saudi Geostationary Satellite 1/Hellas Sat 4 (HS-4/SGS-1) and GSAT-31 with Ariane 5 rocket.

Meanwhile, Arianespace CEO Stephane IsraAl confirmed that the success in post-launch comments from the spaceport’s control room. “For the first Ariane 5 launch of the year, our heavyweight vehicle has once more performed flawlessly,” he was quoted as saying in a statement.

Ten things to know about GSAT-31
