GSAT-6A was a communication satellite launched by the Indian Space Research Organisation (ISRO). It featured a 6-metre (20 ft) unfurlable S-band antenna similar to the one used on GSAT-6.[1] Around 17 minutes after lift-off, the three stage GSLV Mk.II rocket flying on GSLV F08 mission successfully injected the satellite into a geosynchronous transfer orbit.[3] Due to power failure during its orbit raising burns the communication was lost with GSAT-6A[4][5] before it could reach its final circular geostationary orbit (GSO).
