Jason-2, called Ocean Surface Topography Mission (OSTM) by NASA, is a follow-on built by Alcatel using the Proteus bus.

The 506 kg satellite has the third Poseidon Ku/C-band altimeter. Launch 2008 Jun by Delta 2.

Size is 1.0 x 1.0 x 3.7m with 9.7m span, and the 1.2m diameter Poseidon-3 altimeter. hydrazine mass 28 kg.
