Welcome To ISRO :: Launch Vehicles :: GSLV

GSLV-F06 was the seventh mission of Geosynchronous Satellite Launch Vehicle (GSLV) aimed to inject a 2310 kg communication satellite, GSAT-5P, into a Geosynchronous Transfer Orbit (GTO).

The major changes incorporated in compared to the previous flight include loading of 15 tonnes of propellants in its third stage and the uprating of the third stage thrust by 26%. Besides, the overall length of the vehicle was increased by about 1.3 metres.

However, mission was not successful
