Geosynchronous Satellite Launch Vehicle (GSLV)
Geosynchronous Satellite Launch Vehicle (GSLV) is capable of placing 2 ton class of satellites like the INSAT and GSAT series of communication satellites into Geosynchronous Transfer Orbit (GTO).
Geosynchronous Satellite Launch Vehicle Mark-II (GSLV Mk II) is the largest launch vehicle developed by India, which is currently in operation. This fourth-generation launch vehicle GSLV Mk-II has the capability to launch satellites of lift-off mass of up to 2,500 kg to the GTO and satellites of up to 5,000 kg lift-off mass to the LEO. GSLV Mk-II is a 49 m tall, three stage vehicle with a lift-off mass of 416 ton.
The second stage (GS2) is a liquid engine carrying 37.5 tons of liquid propellant.
The third stage is the indigenously built Cryogenic Upper Stage (CUS) which uses typically 15 tons of cryogenic propellants (Liquid Hydrogen (LH2) as fuel and Liquid Oxygen (LOX) as Oxidiser).
