supplementalInformation: OSTM/Jason-2 and Jason-3 are follow-on missions continuing the TOPEX/Poseidon and JASON-1 missions, and are designed to ensure continuity of high quality measurements for ocean science and to provide operational products for assimilation and forecasting applications. The Jason-2 satellite was launched on 20 June 2008, reached its nominal repetitive orbit on 4 July 2008, and ceased acquisition of scientific data on 1 October 2019. After more than 11 years in orbit and well beyond its three- to five-year mission baseline, the Ocean Surface Topography Mission (OSTM) on Jason-2 permanently ceased acquisition of scientific data at 06:48 UTC on 1 October 2019 due to aging-related issues onboard the spacecraft. The Jason-3 satellite was launched on 17 January 2016 from Vandenberg Air Force Base in California, on a SpaceX Falcon 9 launcher, and was placed in the same orbit as OSTM/Jason-2. The satellite went operational on 14 October 2016.

description: Updated information from ICES for the platform JASON-2 from FRANCE and UNITED STATES. Name JASON-2 Country(s) FR: FRANCE; US: UNITED STATES Platform Class 65: Orbiting satellite Commissioned Date 2008-06-20 Decommissioned Date 2016 Information Source (URL) http://www.wmo-sat.info/oscar/satellites/view/205 OTHER INFORMATION: The Ocean Surface Topography Mission (OSTM) is a joint effort by four organizations to measure sea surface height by using a radar altimeter mounted on a low-earth orbiting satellite called Jason-2. The four mission participants are: National Oceanic and Atmospheric Administration (US NOAA), National Aeronautics and Space Administration (US NASA), Centre National d'Etudes Spatiales (FRANCE CNES), and European Meteorological Satellite Organisation (EU EUMETSAT). JASON-2 was built under direction from CNES. After launch by NASA, CNES and NASA transferred operation and control of the JASON-2 platform to NOAA. The Jason-2 satellite was launched in June 20, 2008. Submitted to ICES on 2014-06-04. Confirmed by NOAA on 2018-08-08. After more than 11 years in orbit and well beyond its three- to five-year mission baseline, the Ocean Surface Topography Mission (OSTM) on Jason-2 permanently ceased acquisition of scientific data at 06:48 UTC on 1 October 2019 due to aging-related issues onboard the spacecraft.

description: Description: Altimetry satellite; follow-on of the TOPEX-Poseidon satellite and Jason-1 and Jason-2 satellite missions Country *: FR FRA 250 ISO 3166-2:FR (NODC ATDB=79) Platform Class *: 65-Orbiting satellite Operations/Responsible organization: Centre National d'Etudes Spatiales (CNES) Previous Name: N/A Commissioned Date: (2015-03) Current Length (m): Height: app. 4 meters Notes +: Jason-3 is the fourth mission in U.S.-European series of satellite missions that measure the height of the ocean surface. Scheduled to launch in 2015, the mission will extend the time series of ocean surface topography measurements (the hills and valleys of the ocean surface) begun by the TOPEX/Poseidon satellite mission in 1992 and continuing through the currently operating Jason-1 (launched in 2001) and OSTM/Jason-2 (launched in 2008) missions. These measurements provide scientists with critical information about circulation patterns in the ocean and about both global and regional changes in sea level and the climate implications of a warming world. The primary instrument on Jason-3 is a radar altimeter. The altimeter will measure sea-level variations over the global ocean with very high accuracy (as 1.3 inches or 3.3 centimeters, with a goal of achieving 1 inch or 2.5 centimeters). Continual, long-term, reliable data of changes in ocean surface topography will be generated and will be used by scientists and operational agencies (NOAA, European weather agencies, marine operators, etc.) for scientific research and operational oceanography for the benefit of society. TOPEX/Poseidon and Jason-1 were cooperative missions between NASA and the French space agency, CNES. Additional partners in the Jason-2 mission included NOAA and Eumetsat. Jason-3 continues the international cooperation, with NOAA and Eumetsat leading the efforts, along with partners NASA and CNES. Info Source: https://sealevel.jpl.nasa.gov/missions/jason3/ http://smsc.cnes.fr/JASON3/GP_satellite.htm The Jason-3 satellite was launched on 17 January 2016 from Vandenberg Air Force Base in California, on a SpaceX Falcon 9 launcher, and was placed into the same orbit as OSTM/Jason-2, at an altitude of 1,336 kilometers with an inclination of 66 degrees, to provide virtually blanket coverage of all ice-free ocean surfaces. The satellite went operational on 14 October 2016.
