BackForward Satellite Programme: Satellite for Cartography 

Programme details
Programme description
  • Series of operational satellites for high-resolution land observation.
  • Indian programme: ISRO responsible of development and operations.
  • The platforms are actively stabilised over 3 axes.
  • The design life time is 5 years.
  • The satellites exploit sunsynchronous orbits around 9:30.
  • The replacement policy is based on launching satellites in sequence, roughly 6 months before the expected end-of-life of a satellite.
  • See detailed description at http://www.isro.org/satellites/earthobservationsatellites.aspx.
Data circulation
  • Selected images are stored onboard and downlinked to stations of the ISRO network.
  • Real-time downlink to a network of appointed acquisition stations in X-band.
  • All data concentrated to the National Remote Sensing Center (NRSC) in Hyderabad for processing and distribution.
