GSAT-31 is ahigh-throughputtelecommunication satellite developed by theIndian Space Research Organisation (ISRO).[2]
The satellite's main communication payload isKu band and acts as a replacement of the agingINSAT-4CR.[2] The satellite provides advanced telecommunication to the Indian subcontinent. It is used for VSAT networks, television uplinks, digital signage new gathering,DTH services and other communication systems. This is the 40th communication satellite launched by ISRO and the 22nd launch of ISRO satellite byArianespace.[3][4][5]
