Polar Satellite Launch Vehicle [PSLV]

About 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 Space Capsule Recovery Experiment, Chandrayaan-1, Mars Orbiter Mission, Indian Regional Navigation Satellite System (IRNSS) etc. PSLV remains a favourite among various organisations as a launch service provider and has launched over 60 satellites for 19 countries.

Overview Of PSLV :


Technical Specifications :

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 Nos.
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.

Fuel : HTPB based solid propellant
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.

Engine: Vikas
Fuel : UH25 + N2O4
Max. Thrust : 799 kN
First Stage : PS1

PSLV uses the S139 solid rocket motor that is augmented by 6 solid strap-on boosters.

Engine: S139
Fuel : HTPB based solid propellant
Max. Thrust : 4800 kN
Strap-On Motors

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).

Fuel: HTPB based solid propellant
