The Geosynchronous Satellite Launch Vehicle Mark III (GSLV MkIII) also known as LVM3, is the next generation launcher being developed by ISRO for achieving self-reliance in the launch of 4 ton class of communication satellites to Geosynchronous Transfer Orbits (GTO).
GSLV Mk-III is a 43.43 m tall three stage vehicle with a lift-off mass of 640 tones. The launcher is designed to be a versatile launcher to launch payloads to other orbits as well and will have a payload capability in excess of 10 tons to Low Earth Orbits (LEO). Once GSLV-MkIII becomes operational, India would be able to dispense the procured launches for 4-ton class communication satellites. The powerful cryogenic stage of GSLV Mk III enables it to place heavy payloads into Low Earth Orbits of 600 km altitude. The Cryogenic Upper Stage (C25) is powered by CE-20, India’s largest cryogenic engine, designed and developed by the Liquid Propulsion Systems Centre. GSLV Mk III uses two S200 solid rocket boosters to provide the huge amount of thrust required for lift off. The S200 was developed at Vikram Sarabhai Space Centre.
It will allow India to achieve complete self-reliance in launching satellites as –
It will enhance India’s capability to be a competitive player in the multimillion-dollar commercial launch market. It will help in earning foreign exchange.
The GSLV will help ISRO put heavier communication satellites of GSAT class into orbit.
