GSAT-6A

GSAT-6A is a communications satellite operated by the Indian Space Research Organisation. It features a 6-metre (20 ft) unfurlable S-band antenna similar to the one used on GSAT-6. The first orbit raising maneuver for GSAT-6A was carried out as planned on 30 March 2018 by firing the Liquid Apogee Motor for 2188 seconds from 09:22 AM IST. The second orbit raising maneuver was carried out at 10:00 AM on 31 March 2018. 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. After regaining its track, efforts to re-establish communication with the satellite could not succeed.
