BackForward Satellite Programme: Resurs Operational - 1 

Programme details
Programme description
  • Series of 4 operational satellites, for land observation.
  • Follow-on of (and interleaved with) a long series of experimental satellites named Resurce-F (three sub-series, Resurs-F1, Resurs-F2 and Resurs-F1M), about 60 satellites of the Cosmos family launched in the period 1979-1999.
  • Main improvements over the Resurs-F series: sunsynchronous orbit, longer satellite lifetime and higher altitude.  The operational Resurs-O1 series was prepared by the Meteor-Priroda programme flown in the period 1974-1983.
  • Russian programme: Roscosmos responsible of the development of the space segment, RosHydroMet responsible of operations.
  • The satellites are actively stabilised over 3 axes.
  • The design lifetime is 2 years.
  • The orbit is sunsynchronous around 10:15.
  • The replacement policy is based on launches at roughly 2-year intervals.
  • See detailed description at
Data circulation
  • Data stored onboard and downlinked to RosHydroMet acquisition stations.  Processed and disseminated by RosHydroMet.
