Indian Space Research Organisation (Isro)’s 40th communication satellite Gsat-31 was successfully launched from the European spaceport in French Guiana at 2.31 am on Wednesday (India time).

Ariane 5 VA-247, the launch vehicle of European launch services provider Arianespace, carried India’s GSAT-31 and Saudi Geostationary Satellite 1/Hellas Sat 4 satellites, as scheduled.

After a 42-min flight, GSAT-31 separated from the Ariane 5 upper stage in an elliptical Geosynchronous Transfer Orbit with a perigee (nearest point to Earth) of 250 km and an apogee (farthest point to Earth) of 35,850 km, inclined at an angle of 3.0 degree to the equator, the Indian Space Research Organisation (ISRO) said.

"It gives me great pleasure on the successful launch of GSAT-31 spacecraft onboard Ariane-5," Indian Space Research Organisation's (ISRO) Satish Dhawan Space Centre (SDSC) Director S Pandian said at Kourou soon after the launch.

The GSAT-31 is a "high power" communication satellite with Ku-band, and it is going to serve and replace some of the satellites that are going to expire soon, he said further.

GSAT-31 will be also used for supporting VSAT networks, Television uplinks, Digital Satellite News Gathering, DTH-television services, cellular backhaul connectivity, and many such applications.

Arianespace CEO St phane Isra l tweeted: "2019 is off to a roaring start for #Arianespace! Flight #VA247, carrying Saudi Geostationary Satellite 1/Hellas Sat 4 and GSAT-31, is a confirmed success that underscores our leadership position in the geostationary launch market. @KACST #HellasSat @ISRO @LockheedMartin." 

The next ISRO geostationary satellite to be launched by Arianespace will be GSAT-30.
