Gsat-31 launched from French Guiana

​Before the mission launch, Isro chief K Sivan told TOI, “Gsat-31 will replace Insat-4CR, whose life is expected to end soon. Though Gsat-31 is not a heavy satellite (2,535kg), we are using the services of Arianespace as it is an emergency launch to replace the dying Insat satellite so that communication services are not affected. Gsat-31 satellite can only be launched with GSLV Mk III.
