POLAR SATELLITE LUNCH VEHICLE
The Polar Satellite Launch Vehicle, commonly known by its abbreviation PSLV, is an expendable launch system developed and operated by the Indian Space Research Organisation (ISRO). It 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 PSLV, commercially available only from Russia. PSLV can also launch small size satellites into geostationary transfer orbit (GTO).

In 2015 India successfully launched 17 foreign satellites belonging to Canada, Indonesia, Singapore, the United Kingdom and the United States. Some notable payloads launched by PSLV include India's first lunar probe Chandrayaan-1, India's first interplanetary mission, Mangalyaan (Mars orbiter) and India's first space observatory, Astrosat.
On 15 February 2017, India successfully launched a payload of 104 foreign satellites in polar orbit around the Earth using PSLV tripling the previous record held by Russia for most number of satellites sent to space in a single launch.
