POLAR SATELLITE LAUNCH VEHICLE
About the Launch Vehicle
The PSLV is one of world's most reliable launch vehicles. It has been in service for over twenty years and has launched various satellites for historic missions like Chandrayaan-1, Mars Orbiter Mission, Space Capsule Recovery Experiment, Indian Regional Navigation Satellite System (IRNSS) etc. PSLV remains a favourite among various organisations as a launch service provider and has launched over 40 satellites for 19 countries. In 2008 it created a record for most number of satellites placed in orbit in one launch by launching 10 satellites into various Low Earth Orbits.
|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|
