Jason 1 is the first follow-on mission
to TOPEX/Poseidon. Jason 1 is a joint project of NASA and
CNES. In addition to continuing TOPEX/Poseidon's mission of providing
ocean altimetry data and providing
near-real time altimetry data for predicting sea state and ocean
circulation. Jason 1 will provide sea level and sea state
measurements with turnaround times of hours to days.
Jason-1 is the first satellite
built around the new PROTEUS multimission spacecraft bus. The satellite bus was designed and
built by CNES in cooperation with Alcatel Space Industries.
PROTEUS is a flexible
satellite bus designed to be used to build small satellites in a
modular fashion. The PROTEUS bus, built in Cannes, will remain largely unchanged from
satellite to satellite; the different sensors required for a
specific application being simply added on. PROTEUS is an
acronym for Plate Forme Reconfigurable pour líObservation de la
terre, les Telecommunications et les Utilisations Scientifiques.
The name "Jason" is derived from the leader of the Argonauts in
their search for the golden fleece. The "1"
reflects an expectation that Jason is intended to be the first of
several follow-ons to the TOPEX/Poseidon project.
