GSLV-F08 carrying GSAT-6A spacecraft was launched from Second Launch Pad of Satish Dhawan Space Centre on 29 March 2018, 11:26 UTC and after flight of 17 minutes 45 seconds,[10] placed GSAT-6A into its planned geostationary transfer orbit with 36,692.5 kilometres (22,799.7 mi) apogee, 169.4 kilometres (105.3 mi) perigee and orbital inclination of 20.64°. GSAT-6A spacecraft deployed its solar array after separation from CUS and established contact with ground station.[11]

Asked about GSAT 6A, with which communication had been lost after its launch in March 31 this year, he said ISRO has not given up hope and was still trying to establish radar contact with the satellite. "We have not given up hope. We will wait till a year," he said when asked how much time ISRO would take to announce that the GSAT 6A was a failed mission.

GSAT-11 had the same set of power system configuration that two older satellites had. RISAT-1 died prematurely and GSAT-6A lost communication contact soon after launch on March 29 because of suspected power system failure, harnesses etc.
