Re: Pslv isro

As you asking I am telling Polar Satellite Launch Vehicle, (PSLV) is an expendable launch system developed and operated by the Indian Space Research Organisation (ISRO).

Polar Satellite Launch Vehicle, (PSLV) was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into Sun-synchronous orbits, a service that was, until the advent of the Polar Satellite Launch Vehicle, (PSLV) , commercially available only from Russia. PSLV can also launch small size satellites into geostationary transfer orbit (GTO):
