POLAR SATELLITE LAUNCH VEHICLE

About the Launch Vehicle  Vehicle Specifications

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

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 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.

Fuel : HTPB
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 : 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.

Engine : S139
Fuel : HTPB
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
Max. Thrust : 719 kN
