The PSLV is capable of placing multiple payloads into orbit, thus multi-payload adaptors are used in the payload fairing. This allowed the feat of launching 10 satellites into different orbits in 2008, successfully launched eight satellites into two different orbits in a single mission from the First Launch Pad in 2016 and PSLV-C37 is the 39th flight launched the Cartosat-2 series satellite and 103 co-passenger satellites. More recently, on February 14th, 2022, PSLV C52 launched EOS-04, INS-2TD & InspireSat-1 into their designated orbits successfully
PS4 is the fourth and final stage of pslv and it uses two liquid engines for propulsion. PS4 is responsible for the correct injection of PSLV's payloads into their respective desired orbits.
PS3 is the third and penultimate stage of PSLV, and it uses a HTPB based propellant
PS2 IS THE SECOND STAGE OF PSLV AND IS POWERED BY THE VIKAS LIQUID ENGINE, DEVELOPED IN THE EARLY 90S.
PS1 is the first stage of PSLV and it provides the launcher the high thrust that is required for lift off. It uses the S139 solid rocket booster that contains 139 tonnes of HTPB.
PSLV-XL uses 6 extended strap-ons of 12 tonnes each, the PSLV-CA (core alone version) does not use any strap-on motors, PSLV-DL uses 2 and PSLV QL uses 4.
PSLV earned its title 'the Workhorse of ISRO' through consistently delivering various satellites to Low Earth Orbits. It can take up to 1,750 kg of payload to Sun-Synchronous Polar Orbits of 600 km altitude.
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.
The PS4 is the uppermost stage of PSLV, comprising of two Earth storable liquid engines.
The third stage of PSLV is a solid rocket motor that provides the upper stages high thrust after the atmospheric phase of the launch.
PSLV uses an Earth storable liquid rocket engine for its second stage, know as the Vikas engine, developed by Liquid Propulsion Systems Centre.
PSLV uses the S139 solid rocket motor that is augmented by 6 solid strap-on boosters.
PSLV uses 6,4,2 solid rocket strap-on motors to augment the thrust provided by the first stage in PSLV-XL, QL & DL variants respectively. However, strap-ons are not used in the core alone version (PSLV-CA).
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 a reliable and versatile workhorse launch vehicle of India. The vehicle has launched numerous Indian and foreign customer satellites. Besides, the vehicle successfully launched two spacecraft "Chandrayaan-1 in 2008 and Mars Orbiter Spacecraft in 2013"that later travelled to Moon and Mars respectively. Chandrayaan-1 and MOM were feathers in the hat of PSLV. The launch of PSLV-C48 marks the 50th Launch of PSLV. 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
PSLV earned its title 'the workhorse of ISRO' through consistently delivering various satellites into low earth orbits, particularly the IRS Series of satellites
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
The PSLV is capable of placing multiple payloads into orbit, thus multi-payload adaptors are used in the payload fairing. The payload performance of the vehicle and mission flexibility is evident from the challenging missions where multi-orbit and multi-satellite missions are accomplished. The long string of consecutive successes and multi-satellite launch capability has reinforced the status of PSLV as a reliable, versatile and affordable launcher in the global market
