Polar Satellite Launch Vehicle (PSLV) is the third era dispatch vehicle of India. It is the principal Indian dispatch vehicle to be furnished with fluid stages. After its first effective dispatch in October 1994, PSLV arose as the solid and adaptable workhorse dispatch vehicle of India with 39 sequentially fruitful missions by June 2017. During 1994-2017 period, the vehicle has dispatched 48 Indian satellites and 209 satellites for clients from abroad.
Plus, the vehicle effectively dispatched two space apparatus – Chandrayaan-1 out of 2008 and Mars Orbiter Spacecraft in 2013 – that later went to Moon and Mars separately.
PSLV acquired its title 'the Workhorse of ISRO' through reliably conveying different satellites to Low Earth Orbits, especially the IRS arrangement of satellites. It can take up to 1,750 kg of payload to Sun-Synchronous Polar Orbits of 600 km height.
Because of its unparalleled dependability, PSLV has additionally been utilized to dispatch different satellites into Geosynchronous and Geostationary circles, similar to satellites from the IRNSS heavenly body.
The PS4 is the highest phase of PSLV, involving two Earth storable fluid motors.
The third phase of PSLV is a strong rocket engine that gives the upper stages high push after the environmental period of the dispatch.
PSLV utilizes an Earth storable fluid rocket motor for its subsequent stage, know as the Vikas motor, created by Liquid Propulsion Systems Center.
PSLV utilizes the S139 strong rocket engine that is increased by 6 strong lash on sponsors.
PSLV utilizes 6 strong rocket tie on engines to expand the push given by the first stage in quite a while PSLV-G and PSLV-XL variations. Be that as it may, tie ons are not utilized in the center alone form (PSLV-CA).
