POLAR SATELLITE LAUNCH VEHICLE
About the Launch Vehicle
Polar Satellite Launch Vehicle (PSLV) is the third generation launch vehicle of India. It is the first Indian launch vehicle to be equipped with liquid stages. After its first successful launch in October 1994, PSLV emerged as the reliable and versatile workhorse launch vehicle of India with 39 consecutively successful missions by June 2017. During 1994-2017 period, the vehicle has launched 48 Indian satellites and 209 satellites for customers from abroad.
Besides, the vehicle successfully launched two spacecraft – Chandrayaan-1 in 2008 and Mars Orbiter Spacecraft in 2013 – that later traveled to Moon and Mars respectively
|Height||: 44 m|
|Diameter||: 2.8 m|
|Number of Stages||: 4|
|Lift Off Mass||: 320 tonnes (XL)|
|Variants||: 3 (PSLV-G, PSLV - CA, PSLV - XL)|
|First Flight||: September 20, 1993|
Payload to SSPO: 1,750 kg
PSLV earned its title 'the Workhorse of ISRO' through consistently delivering various satellites to Low Earth Orbits, particularly the IRS series of satellites. It can take up to 1,750 kg of payload to Sun-Synchronous Polar Orbits of 600 km altitude.
Payload to Sub GTO: 1,425 kg
Due to its unmatched reliability, PSLV has also been used to launch various satellites into Geosynchronous and Geostationary orbits, like satellites from the IRNSS constellation.
Fourth Stage: PS4
The PS4 is the uppermost stage of PSLV, comprising of two Earth storable liquid engines.
|Engine||: 2 x PS-4|
|Fuel||: MMH + MON|
|Max. Thrust||: 7.6 x 2 kN|
Third Stage: PS3
The third stage of PSLV is a solid rocket motor that provides the upper stages high thrust after the atmospheric phase of the launch.
|Max. Thrust||: 240 kN|
Second Stage: PS2
PSLV uses an Earth storable liquid rocket engine for its second stage, know as the Vikas engine, developed by Liquid Propulsion Systems Centre.
|Fuel||: UDMH + N2O4|
|Max. Thrust||: 799 kN|
First Stage: PS1
PSLV uses the S139 solid rocket motor that is augmented by 6 solid strap-on boosters.
|Max. Thrust||: 4800 kN|
PSLV uses 6 solid rocket strap-on motors to augment the thrust provided by the first stage in its PSLV-G and PSLV-XL variants. However, strap-ons are not used in the core alone version (PSLV-CA).
|Max. Thrust||: 719 kN|
