  • The satellite will provide services in the field of Agriculture, Forestry and Disaster Management.
  • The mission life of RISAT-2BR1 is 5 years.


Cooperation with other Countries:

  • Along with the RISAT-2bR1 the nine customer satellites of Israel, Italy, Japan and the USA were precisely injected into their designated orbits.

About PSLV

  • The Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). 
  • It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun-synchronous orbits, a service that was, until the advent of the PSLV in 1993, commercially available only from Russia.
  • It has 4 stages with 1st and 3rd being Solid and 2th and 4th being Liquid stage
  • PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO).
  • Most notable among the launches was the launch of PSLV C37 which successfully deployed 104 satellites in sun-synchronous orbit, tripling the previous record held by Russia for the highest number of satellites sent to space on a single launch.
  • The PSLV has a history of successful launches of payloads that include Chandrayaan-1, Mars Orbiter Mission and the space recovery mission
