BackForward Satellite Programme: RadarSat Constellation Mission 

Programme details
Programme description
  • Three-satellite programme for SAR observation.  Follow-on of RadarSat.  Improvements: more performing instrument, more agile mission, smaller platform.
  • Canadian programme: CSA responsible of development and operations, supported by the private sector.
  • The platforms are actively stabilised over 3 axes.
  • The design life time is 7 years.
  • The satellites exploit sunsynchronous dawn-dusk orbits at 6:00.
  • The 3 satellites are launched at short time intervals, to fly in formation (dephased by 120°) for larger composite swath (thus shorter revisit time), interferometry and redundancy.
  • See detailed description at
Data circulation
  • Onboard stored data are transmitted to Prince Albert (Saskatchewan), and Gatineau (Quebec).
  • Real-time data are transmitted to several appointed ground stations.
  • Data processing is performed at the Canadian Data Processing Facility (CDPF) in Gatineau, operated by the Geospatial Services of MDA (MacDonald Dettwiler Associates Ltd) (formerly RADARSAT International Ltd).
