ISRO’s SSLV satellite

Date: 29 January 2022 Tags: Space


The maiden development flight of ISRO’s indigenous launch rocket, the Small Satellite Launch Vehicle (SSLV) will soon be conducted.



  • The SSLVs are especially earmarked for the launch of small satellites into low earth orbits. Its demand has grown to cater to developing countries, private corporations, and universities for small satellites.

  • Till now, launch of small satellites is carried out as ‘piggy-back’ along with large satellites on ISRO’s Polar Satellite Launch Vehicle.

  • Because of this, the contract for small satellites is dependent on the finalising of launch contracts for the larger satellites by ISRO.


Capabilities of SSLV

  • SSLV has the capability to carry satellites weighing up to 500 kg to a low earth orbit whereas PSLV can carry a payload of up to 1000 kg.

  • It can be integrated within 72 hours unlike existing 60-70 days. This ensures that satellites can be launched on short notice.

  • The cost of launching a satellite will come down to 30 crores. It will be an on demand vehicle based on customers.



  • The SSLV is perfectly suited for launching multiple microsatellites at a time and supports multiple orbital drop-offs. 

  • It is expected that 15-20 SSLVs are required every year to cater to domestic demands itself.


Private partnership

  • The government of India recently created New Space India Limited (NSIL) with an aim to use research and development carried out by ISRO for commercial purposes through Indian industry partners.

  • At present, around 500 industries are involved in contributing to ISRO’s programs. Half of the budget flows to these industries.



PSLV is an indigenously developed four-stage rocket propulsion system comprising a combination of solid and liquid-fuelled rocket stages. 



GSLV is a three-stage rocket propulsion system that is designed to carry a heavier payload into outer space.
