CNES Strategy in OceanographyCNES 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

Status of altimetry missions/activitiesStatus 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)

Jason1Jason1
■ 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

■ 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/AltiKaSARAL/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)
