What is GSL?

The Geosynchronous Satellite Launch Vehicle (GSLV) is a series of expendable launch vehicles developed and operated by the Indian Space Research Organisation (ISRO). Designed to place satellites into geosynchronous transfer orbits (GTO), the GSLV enables India to launch heavy communication and Earth observation satellites into high-altitude orbits. The vehicle uses a combination of solid, liquid, and cryogenic stages, with the indigenously developed cryogenic upper stage being a landmark achievement for India's space programme. First launched in 2001, the GSLV has undergone several upgrades, most notably the GSLV Mk III (now called LVM3), which can carry payloads of up to 4,000 kg to GTO and has been used for missions like Chandrayaan-2 and the OneWeb satellite constellation. The GSLV is crucial for India's self-reliance in space technology, reducing dependence on foreign launch providers. In competitive exams like UPSC and ISRO recruitment, the GSLV is often cited as an example of indigenous cryogenic engine technology and strategic space capability. It is regularly used for both domestic and commercial satellite launches from the Satish Dhawan Space Centre in Sriharikota.

GSL — frequently asked questions

What is the full form of GSL?
The full form of GSL is Geosynchronous Satellite Launch Vehicle, a series of launch vehicles developed by ISRO to place satellites into geosynchronous orbits.
How is GSL different from PSLV?
GSL is designed for heavier payloads (up to 4,000 kg) to geosynchronous orbit, while PSLV is used for lighter payloads (up to 1,750 kg) to low Earth and polar orbits. GSL uses a cryogenic upper stage, whereas PSLV uses liquid engines.
What are the versions of GSL?
ISRO has developed the GSLV Mk I, Mk II, and the more powerful GSLV Mk III (now renamed LVM3). The Mk II uses an indigenous cryogenic stage, and Mk III has a higher payload capacity for heavy satellites.
