Jason-1

Jason-1 is a project realized from the collaboration between NASA and CNES, and it is considered the successor of TOPEX/Poseidon. Launched in December 2001, Jason-1 flew on a non-Sun-synchronous, circular orbit, at altitude 1336 km and inclination 66.038°. During this first phase of the mission, its ground-track was the same as TOPEX, with a repeat cycle of 9.9156 days. In May 2012 Jason-1 moved into a geodetic orbit until the end of the mission in June 2013.
