  1. CNES program status E. Thouvenot, CNES March 2007

  2. CNES Strategy in Oceanography • Contribute to operational outcome of altimetry :  TOPEX/POSEIDON => JASON1 => JASON2/OSTM =>JASON3 ERS 1 & 2 => ENVISAT => SENTINEL3 + CORIOLIS, MERCATOR/COO/ECOMF, ... • Continue research activities for future altimetry missions/instruments (AltiKa, WSOA, Water,…) • Contribute to space measurements of other ocean physical parameters : • - salinity : SMOS, CNES contribution to ESA project • - directional wave spectrum (SWIM/CFOSAT) - ocean colour (SSO or GEO) • Prepare ocean applications of ORFEO (Cosmo SkyMed/Pleiades) : mainly coastal applications CNES program status – OST-ST meeting - Hobart - March, 2007

PLEIADES (CNES) DORIS 2010 CRYOSAT2 (ESA) DORIS SALP : Altimetry and precise positioning service operational MERCATOR : assimilation, forecast CNES / SHOM / METEOFRANCE / IFREMER / CNRS / IRD CNES program status – OST-ST meeting - Hobart - March, 2007

  4. Status of altimetry missions/activities • TOPEX/POSEIDON : • Stopped after more than 13 years of ocean observations • Jason1/TOPEX tandem mission : success ! • ENVISAT • excellent synergy with Jason1 (T/P and ERS complementarity further improved) • DORIS • 5 DORIS receivers simultaneously in flight : earth reference system strengthened • MERCATOR • inter Agency structure for the implementation of an oceanographic forecasting center in Europe in the mid term (GMES Marine Core Service) • AltiKa : Implementation phase approved. Launch possible from end-2009. • SALP/SSALTO/AVISO : multi-mission ground segment • Next Step : possible contribution(s) to HY-2A/Water/SENTINEL3/JASON3 (TBD) • Important notice to OST-ST members : new Research Announcement for the next 4-years : NASA AO : see ROSES. CNES/EUMETSAT AO : see AVISO website • New team in place early 2008 (before Jason2/OSTM launch) CNES program status – OST-ST meeting - Hobart - March, 2007

  5. AVISO Data user teams CNES program status – OST-ST meeting - Hobart - March, 2007

  6. Jason1 • Qualified in orbit • Operational mission underway • Products distributed routinely • CNES operations funded through SALP • Required lifetime : 3 years (achieved in december, 2004) • Extended mission: 5 years (achieved in december, 2006) • Extension agreement for 5 more years of operation signed between CNES & NASA on december, 2006 CNES program status – OST-ST meeting - Hobart - March, 2007

  7. Jason2/OSTM European side • Cooperative Framework between NOAA/NASA/EUMETSAT/CNES • basic mission, continuation of Jason1 (Core Mission) • Technological passengers to enhance DORIS performance (CARMEN2/LPT, T2L2) • 4-party MOU signed • LPT CNES/JAXA MOU signed • CNES • program approved in April, 2004 • EUMETSAT • program approved in June, 2003 • CNES/EUMETSAT agreement signed Launch date : june 15, 2008 CNES program status – OST-ST meeting - Hobart - March, 2007

  8. SARAL/AltiKa • Program approved on december, 2005 • Altimetric Gap filler between ENVISAT & SENTINEL3 • Research oriented mission : - new, higher frequency, greater performance - potential new applications on ice, land, coast areas • …but with a consolidated architecture : conventional altimeter • Cooperative framework : CNES/ISRO • Initially, AltiKa wa supposed to be embarked on OCEANSAT3 mission (with other ocean-dedicated sensors…) • However, delay on OCEANSAT3 schedule • May/June 2006 : CNES&ISRO proposition to embark AltiKa payload with Argos3, on a new platform, named SSB (Small Satellite Bus), which is presently being developed by ISRO. • July2006/November2006 : CNES&ISRO technical studies to assess the feasibility : ok • Confirmation of CNES&ISRO cooperation on this new baseline obtained on December 2006 : SARAL mission (Satellite with ARgos & ALtika) • CNES/ISRO MOUs signed in february, 2007 • Tentative launch date : end-2009/early-2010 • Data policy : ~ the same as JASON missions (through CNES/ISRO RAs) CNES program status – OST-ST meeting - Hobart - March, 2007

  10. DORIS Next Steps • HY-2A : CNES/CNSA discussions underway • Payload : Dual frequency altimeter, nadir 3-frequency radiometer, 5-frequency scanning radiometer, scanning scatterometer, +DORIS/GPS/LRA • Orbit : SSO 6am-6pm, 14 days (after 1-year geodetic mission) • Launch : 2009 • JASON3 : (see dedicated presentation) • NOAA/EUMETSAT cooperation with EC, CNES & NASA (TBC) contributions • CNES in-kind contribution : Proteus platform and project team equivalent to JASON/OSTM (i.e. about one third of European part of the program) • Launch : end-2012 • WATER (or SWOT) : CNES/NASA discussions underway • Ku/C nadir altimeter (SRAL) + Ka-band wide-swath SAR-altimeter • Phase 0 in 2007 (CNES/JPL) • Cooperation scheme TBD • Launch : 2013-2016 timeframe • and contributions to ESA/EC missions : Cryosat2, Sentinel3 (TBD) : see dedicated presentation CNES program status – OST-ST meeting - Hobart - March, 2007
