BackForward Satellite Programme: Active Cavity Radiometer Irradiance Monitor Satellite 

Programme details
Programme description
  • Single satellite programme to monitor solar irradiance.
  • USA programme: NASA responsible of development and operations.
  • The platform is spin-stabilised, with the spin axis pointing at Sun.
  • The design life time of the satellite isĀ 5 years.
  • The satellite exploits a sunsynchronous around 11:00.
  • It provides continuity of solar irradiance observation from previous satellites (e.g. UARS) to JPSS-FF.
  • See detailed description at http://acrim.jpl.nasa.gov.
Data circulation
  • Onboard stored data downlinked to the ACRIMSAT ground station located at the JPL / Table Mountain Facility.
  • Data processed at the NASA Jet Propulsion Laboratory (JPL), Pasadena CA.
