Definition
The Geosynchronous Satellite Launch Vehicle (GSLV) is a large launch vehicle series developed by the Indian Space Research Organisation (ISRO), primarily used for placing satellites into geostationary transfer orbit (GTO) and geostationary orbit (GEO). Development of the GSLV began in 1987, with the Mark II and Mark III variants achieving successive successful launches in the early 21st century.
Technical Specifications
| Parameter | GSLV Mark II | GSLV Mark III |
|---|---|---|
| GTO Payload Capacity | ~2,500 kg | ~4,000 kg |
| GEO Payload Capacity | ~2,000 kg | ~3,000 kg |
| Vehicle Type | Liquid/Cryogenic Upper Stage | Liquid/Cryogenic Upper Stage |
Primary Applications
The GSLV is mainly used for launching geostationary orbit satellites:
- Communications satellites: Launching large communications satellites to geostationary orbit
- Navigation augmentation: Supporting the IRNSS system by launching navigation augmentation satellites
- Meteorological satellites: Launching weather observation satellites
Connection to Cislunar Space
The GSLV has the capability to launch satellites into geostationary orbit, which is one of the important orbital regions within cislunar space. Situational awareness in the vicinity of geostationary orbit is an essential component of the cislunar space awareness architecture.
