BackForward Satellite Programme: Community Initiative for Continuing Earth Radio Occultation 

Programme details
Programme description
  • Constellation of satellites (24 at regime) for radio occultation sounding.
  • Commercial programme implemented by GeoOptics, Pasadena, CA, USA.  Data possibly bought by NOAA.
  • The platforms are actively stabilised over 3 axes.
  • The design life time is 7 years for individual satellites, undetermined for the full constellation.
  • The replacement policy is based on launching a new satellite cluster before the status of the constellation is unacceptably degraded, taking advantage of launch opportunities.
  • The orbit heights, ranging from 500 to 600 km, and inclinations, are determined by the launch opportunity.
  • See detailed description at https://directory.eoportal.org/web/eoportal/satellite-missions/c-missions/cicero
Data circulation
  • The data are made available by GeoOptics, Pasadena, CA, USA, on a commercial basis.
