The PSLV is Polar Satellite Launch Vehicle. ISRO (Indian Space Research Organization) is building and maintaining this Indian adjustable launch vehicle. It is India’s first liquid-stage satellite launch vehicle and the third generation launch vehicle. To enable India to launch its IRS (Indian Remote Sensing) satellites into Sun-synchronous orbits, PSLV was developed. This method could potentially find small GTO (geostationary transfer orbit) satellites.
- India launched 104 satellites into a polar orbit around the Earth on February 15, 2017, using the PSLV rocket.
- From 1994 to 2017, India used the PSLV to launch 48 domestic spacecraft and 209 foreign satellites.
- It was also found alongside India’s two spacecraft, the Chandrayan-1 in 2008 and the Mars Orbiter in 2013.
- Eventually, these spacecraft made their way to Mars and the Moon.

PSLV Characteristics
Below is a list of the PSLV’s primary specifications:
- The vehicle is 44 metres tall
- The car has a 2.8 m diameter
- 320 tonnes of mass are lifted
- There are four stages
- The three types are PSLV-G, PSLV-CA, and PSLV-XL
- The car made its debut on September 20, 1993
PSLV’s Technical Specifications
- Since it successfully launched numerous satellites to Low Earth Orbits again and time again, the PSLV has become well-known as the ISRO Workhorse, or IRS sequence of the Satellites.
- At the height of 600 km, a load of up to 1,750 kg can be carried to the Sun-Synchronous Polar Orbits.
- Six solid rocket strap-on engines are included in its PSLV-G and PSLV-XL versions to increase the thrust of the first stage.
- It is a four-stage launch vehicle that alternates uses liquid and solid propulsion systems; for example, the first and third stages use Strong rocket motors. In contrast, the second and fourth stages employ liquid rocket engines.
- PS1 (First Stage) – Six solid strap-on boosters are added to the S139 reliable rocket motor, which powers the first stage. The most significant thrust generated in this method is 4800 kN.
- PS2 (Second Stage) – An Earth-storable liquid rocket engine was employed for this stage. The Liquid Propulsion System Centre is creating what is known as the Vikas engine. The greatest thrust generated in this method is 799 kN.
- PS3 (Third Stage) – After the launch’s atmospheric phase, a solid rocket motor provides the necessary thrust for the PSLV’s this stage. The most significant thrust generated in this method is 240 kN.
- PS4 (Fourth Stage) – It has two liquid engines within, which can be kept on Earth. The most significant thrust generated in this technique is 7.6 x 2 kN.
