GSAT-6A was a communication satellite launched by the Indian Space Research Organisation (ISRO).

[9] 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.

[10] The first orbit raising maneuver for GSAT-6A was carried out as planned on 30 March 2018 by firing the Liquid Apogee Motor (LAM) for 2188 seconds from 09:22 AM IST.

As the satellite was on-course for its third and final orbit raising maneuver on 1 April 2018, communication with it was lost and the spacecraft was temporarily untraceable.
