ISRO successfully launched INSAT-4E on 27 August 2015, using a GSLV D6 Mk.II rocket flying from the Satish Dhawan Space Centre and inserted into a Geostationary Transfer Orbit (GTO) with injection parameters of 170 km x 35945 km, 19.96 degree inclination.

[10] Third orbit raising operation of GSAT-6 was successfully completed by firing the Apogee Motor for 580.32 seconds at 07:46 hours IST on Aug 30, 2015.

GSAT-6 was successfully positioned in its orbital slot of 83 degree east and collocated with INSAT-4A, GSAT-12, GSAT-10 and IRNSS-1C on September 6, 2015, morning, after carrying out four drift arresting maneuvers.

[12] According to Comptroller and Auditor General of India report submitted to parliament in 20 December 2022, the GSAT-6 satellite has remained largely underutilized since its launch in August 2015 which is almost half of the expected operational life of 12 years.
