GEOSYNCHRONOUS SATELLITE LAUNCH VEHICLE
About the Launch Vehicle
The Geosynchronous Satellite Launch Vehicle was primarily developed to launch INSAT class of satellites into Geosynchronous Transfer Orbits. GSLV is being used for launching GSAT series of satellites. GSLV is a three stage launcher that uses one solid rocket motor stage, one Earth storable liquid stage and one cryogenic stage. The most recent flight of GSLV, the GSLV-D5, placed GSAT-14 into its planned orbit and marked the first successful flight of the indigenous cryogenic stage. Earlier, GSLV had launched various communication satellites among which EDUSAT is notable, being India's first satellite built exclusively to serve the educational sector through satellite based distance education.
|Height||: 49.13 m|
|Number of Stages||: 3|
|Lift Off Mass||: 414.75 tonnes|
|First Flight||: April 18, 2001|
Payload to GTO: 2,500 kg
GSLV's primary payloads are INSAT class of communication satellites that operate from Geostationary orbits and hence are placed in Geosynchronous Transfer Orbits by GSLV.
Payload to LEO: 5,000 kg
Further, GSLV's capability of placing up to 5 tonnes in Low Earth Orbits broadens the scope of payloads from heavy satellites to multiple smaller satellites.
Third Stage: CUS
Developed under the Cryogenic Upper Stage Project (CUSP), the CE-7.5 is India's first cryogenic engine, developed by the Liquid Propulsion Systems Centre. CE-7.5 has a staged combustion operating cycle.
|Fuel||: LOX + LH2|
|Max. Thrust||: 75 kN|
|Burn-time||: 720 sec|
Second Stage: GS2
One Vikas engine is used in the second stage of GSLV. The stage was derived from the PS2 of PSLV where the Vikas engine has proved its reliability.
|Fuel||: UDMH + N2O4|
|Max. Thrust||: 800 kN|
|Burntime||: 150 sec|
First Stage: GS1
The first stage of GSLV was also derived from the PSLV's PS1. The 138 tonne solid rocket motor is augmented by 4 liquid strap-ons.
|Max. Thrust||: 4700 kN|
|Burntime||: 100 sec|
The four liquid engine strap-ons used in GSLV are heavier derivatives of PSLV's PS2, and use one Vikas engine each.
|Fuel||: UDMH + N2O4|
|Max. Thrust||: 680 kN|
|Burntime||: 160 sec|
