Programme details
Programme description
  • Series of satellites for scientific missions and technological demonstrations.
  • Argentinean programme: CONAE responsible of development and operations, payloads often provided by collaborating agencies.
  • The platforms are actively stabilised over 3 axes.
  • The design life time is 5 years.
  • The satellites exploit different orbits depending on the mission.  Drifting orbits for non-EO missions (SAC-A and SAC-B).  For Earth observation, sunsynchronous orbits around 10:30 or 6:00 are used.
