Satellite Programme: Joint Altimetry Satellite Oceanography Network
Programme details
Programme description
Series of three operational satellites for ocean altimetry.
International programme: initiated by NASA and CNES with JASON-1 as follow-on of TOPEX-Poseidon, then joined by EUMETSAT and NOAA.
The platforms are actively stabilised over 3 axes.
The design life time of the satellites is 5 years.
The satellites are placed in a medium-height, 66° inclination orbit, particularly stable, suitable for geodetic purposes.
The replacement policy is based on launching satellites in sequence, roughly 6 months before the expected end-of-life of a satellite.
