DoSISRO has been providing Launch services for customer satellites since 1999 onboard ISRO’s Polar Satellite Vehicle (PSLV). Till June 2019, 319 customer satellites from 33 countries have been launched onboard PSLV on commercial basis through its commercial arm . In September 2016, PSLV C-37 has successfully injected 104 satellites into orbit – the highest number of satellites launched in a single mission so far. PSLV is a versatile vehicle, capable of launching satellites into LEO (Low Earth Orbit) , SSO, Sub-GTO, GTO (Geosynchronous Transfer Orbit) Orbits. With ISRO operationalising its Geosynchronous Satellite Launch Vehicle (GSLV) and LVM3 and building Small Satellite Launch Vehicle (SSLV), as a launch on demand Vehicle, NSIL is in a position to offer and expand its launch services.
FLP was built in the early 1990’s following the concept of Integrate on the Pad, wherein, after assembling the rocket, a 3200ton Mobile Service Tower (MST), moves backward to it’s parking place.The facility is well equipped to handle the storage, transport and servicing of both earth storable and cryopropellants.
SLP, which became operational in 2005 was conceived and implemented as a facility upgradation to support for the increasing launch demands that ISRO was facing. Built by Mecon Limited, a Govt of India enterprise located at Ranchi, Jharkhand, the SLP follows the Integrate, Transfer and Launch concept, wherein, the vehicle after getting assembled on a Mobile Launch Pedestal in the Vehicle Assembly Building is moved to the launch pad in a vertical position, on a rail track.
