Geosynchronous Satellite Launch Vehicle (GSLV-F10) will launch Geo Imaging Satellite (GISAT-1) from the Second Launch Pad of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. Weighing about 2268 kg, GISAT-1 is the first state-of-the-art agile Earth observation satellite which will be placed in a Geosynchronous Transfer Orbit by GSLV-F10. Subsequently, the satellite will reach the final geostationary orbit using its onboard propulsion system. A 4 metre diameter O shaped payload fairing is being flown for the first time in this GSLV flight. This is the fourteenth flight of the GSLV. Operating from geostationary orbit, GISAT-1 will facilitate near real time observation of the Indian sub-continent, under cloud free condition, at frequent intervals.
