Launch and early orbit phase

Jason-3 was launched from the American Air Force base in Vandenberg, California, USA on 2016/01/17. The launcher chosen by NASA is the Falcon 9 rocket from Space X, which is certified to launch this satellite. Once the satellite is separated, the early orbit phase and acceptance testing is carried out by Cnes in Toulouse.

See below the highlights of this successful launch.

Jason-3 in orbit 

2016/01/17: Flying from Vandenberg Air Force Base, the SpaceX Falcon9 rocket lifted off with the Jason-3 spacecraft at 18:42 UTC. The attempt to land the first stage on the ASDS in the Pacific Ocean was unsuccessful. [more]

Jason-3 Doris instrument switched on

2016/01/18: The DORIS instrument has been successfully switched ON today at 5:40 UTC. The instrument behavior is fully nominal and has started to compute the on-orbit solutions thanks to the DIODE software.[more]

Jason-3 mission successfully launched, Release Press from Cnes

Jason-3 mission returns first data

2016.01.19: Jason-3 was successfully launched Sunday 17 January. All the instruments were rapidly switched on. The first real-time Jason-3 data product was generated and compared with Jason-2, less than three days after launch. [<link en news front-page-news>more]

Injection in orbit

Injection orbit is 25 km below the nominal Jason-3 orbit to avoid polluting the operational orbit and to avoid to cross the Jason-2 orbit (and Jason-1). The duration for station acquisition and number of maneuvers depends on the launch date  (day number in the Jason cycle), and on the launcher dispersions. The target duration for this station acquisition should not exceed 1 month.
