GSLV (Geosynchronous Satellite Launch Vehicle)
India's latest four-stage launch vehicle, capable of placing 2,500-kg Insat-type
communications satellites into geostationary transfer orbit. The GSLV improves
on the performance of the PSLV (Polar Satellite
Launch Vehicle) by the addition of liquid strap-on boosters and a cryogenic
upper stage. The solid first and liquid second stages are carried over from
the PSLV, while the cryogenic upper stage is being supplied by Russia until
India has developed an indigenous version. Carrying a 1.5-ton experimental
satellite, the GSLV was launched successfully for the first time on Apr.
18, 2001 – an important first step toward India's independence in
space and competing in the lucrative geosynchronous market.
