Success of PSLV in the History of Indian Space Research Organization

The main theory of this paper is importance and success of polar satellite launching vehicle (PSLV) in the Indian Space Research Organization. This paper explains the different stages and important elements of PSLV. So far Indian Space Research Organization launched total 65 satellites in them foreign satellites were 35. The recent PSLV C23 launched the 5 foreign satellites . The Polar Satellite Launch Vehicle is an expendable launch system developed and operated by the Indian Space Research Organization . It was developed to allow India to launch its Indian Remote Sensing 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 .As of 2014 the PSLV has launched 65 satellites into a variety of orbits. Some notable payloads launched by PSLV include India's Chandrayaan-1 lunar probe and the Mars Orbiter Mission. It is the most successful launch vehicle in ISRO. PSLV is the first operational launch vehicle of ISRO. PSLV is capable of launching 1600 kg satellites in 620 km sun-synchronous polar orbit and 1050 kg satellite in geo-synchronous transfer orbit. In the standard configuration, it measures 44.4 m tall, with a lift off weight of 295 tones. 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 tones of propellant. A cluster of six strap-on attached to the first stage motor, four of which are ignited on the ground and two are air-lit. India's Space Research Organization introduced the Polar Satellite Launch Vehicle series in 1993. PSLV, designed to lift 1.5 metric ton satellites to sun synchronous polar orbit from Satish Dhawan Space Centre, SHAR, Sriharikota, India, is a conglomerate of Indian and other countries components.PSLV performance was progressively improved during the 1990s. The operational "C" version, first flown in 1997, stands 44.4 meters tall and weighs 295 metric tons at liftoff. It consists of four stages that use solid and liquid propellants alternately.
