PSLV Vehicles

PSLV means Polar Sateliite Launch Vehicles.It is first operational and introduced launch vehicle of ISRO. The PLSV is launching 1600kg satellites into Sun-synchronous orbit.The Sun-synchronous orbit is above 620km from Earth surface and it is launching 1050kg satellites into Geo-synchronous orbit. PLSV contains standard features and configurations.It measures 44.4 m tall, with a lift off weight of 295 tonnes. PSLV has four stages using solid and liquid propulsion systems alternately. The first stage is one of the largest solid propellant boosters in the world and carries 139 tonnes of propellant. A cluster of six strap-ons attached to the first stage motor, four of which are ignited on the ground and two are air-lit.

The reliability rate of PSLV has been superb. There had been 21 continuously successful flights of PSLV, till September 2012 . With its variant configurations, PSLV has proved its multi-payload, multi-mission capability in a single launch and its geosynchronous launch capability. In the Chandrayaan-mission, another variant of PSLV with an extended version of strap-on motors, PSOM-XL, the payload haul was enhanced to 1750 kg in 620 km SSPO. PSLV has rightfully earned the status of workhorse launch vehicle of ISRO.

Till now, The launched PLSV vehicles are PLSV-D1,PLSV-D2, PLSV-D3, PLSV-C1, PLSV-C2,PLSV-C3, PLSV-C4, PLSV-C5, PLSV-C6, PLSV-C7, PLSV-C8, PLSV-C9, PLSV-C10,PLSV-C11, PLSV-C12, PLSV-C14, PLSV-C15, PLSV-C16, PLSV-C17, PLSV-C18, PLSV-C19, PLSV-C21.
