Geosynchronous Satellite Launch Vehicle (GSLV)
Context
In preparation for the upcoming launch of the NASA-ISRO joint NISAR satellite, ISRO announced that the satellite had been successfully integrated with the Geosynchronous Satellite Launch Vehicle (GSLV) and that all systems of the rocket had undergone comprehensive checks.
Overview of GSLV
The GSLV is a space launch vehicle developed and operated by the Indian Space Research Organization (ISRO), designed to deploy satellites and other payloads into Geosynchronous Transfer Orbits (GTOs). Compared to the Polar Satellite Launch Vehicle (PSLV), the GSLV can carry significantly heavier payloads.
- Dimensions & Structure:
- Height: 49.13 meters (ISRO’s tallest launch vehicle)
- Lift-off mass: 420 tonnes
- Three stages: solid first stage with four liquid strap-on boosters, liquid second stage, and a cryogenic third stage.
- Stage Details:
- First Stage: S139 solid booster with 138 tonnes of propellant, supported by four liquid strap-on motors carrying 40 tonnes of propellant.
- Second Stage: Liquid engine with 40 tonnes of liquid propellant.
- Third Stage: Indigenous Cryogenic Upper Stage (CUS) using 15 tonnes of cryogenic propellant.
The GSLV enhances PSLV’s capability by incorporating liquid strap-on boosters and a cryogenic upper stage. While the solid and liquid stages are adapted from the PSLV, the cryogenic upper stage was initially supplied by Russia until ISRO developed its own indigenous version.
Variants of GSLV
- GSLV Mk I:
- First-generation variant with a payload capacity of 2–2.5 tonnes to GTO.
- Utilized Russian cryogenic upper stage due to early challenges in indigenous cryogenic technology.
- Conducted around five launches (2001–2010), including suborbital tests, with the last flight in 2010.
- GSLV Mk II:
- Improved model with an indigenously developed cryogenic upper stage.
- Payload capacity around 2.5 tonnes to GTO.
- First successful launch in 2014.
- GSLV Mk III (LVM-3):
- Most powerful and advanced variant, currently operational.
- Can carry payloads up to 4 tonnes to GTO.
Performance and Notable Missions
The GSLV has launched numerous important satellites, including communication satellites such as INSAT and GSAT, navigation satellites from the NavIC series, and Earth observation satellites like IDRSS. Some prominent missions are:
- The South Asia Satellite (2017)
- Military communication satellite (2018)
- Chandrayaan-2 lunar mission (2019)
