The Ocean Surface Topography Mission on the Jason-2 satellite (OSTM/Jason-2) is a follow-on to the Jason-1 mission. It launched 20 June 2008 from Vandenburg Air Force Base in California.

The Jason-2 payload includes the next generation of Poseidon altimeter (Poseidon-3, with the same general characteristics than Poseidon-2, but with a lower instrumental noise, an algorithm enabling a better tracking over land and ice, and the Doris location system. The accuracy should be of about 2.5 cm on the altimeter measurements.

Three new instruments (T2L2, LPT, Carmen-2) are moreover onboard, to study radiations in the satellite environment (LPT, Carmen-2), and to measure a laser path delay. Besides their scientific interest, these instruments should allow to enhance data quality and accuracy.
