The EPS Programme Within IJPS The EUMETSAT Polar System (EPS) is the European contribution to the Initial Joint Polar System (IJPS) established with NOAA; The IJPS will provide global meteorological and climate data from a series of European and American sun-synchronous polar orbiting satellites, comprising NOAA N&N´and Metop 1 & 2. EUMETSAT has established Co-operation Agreements with: ESA, for the development and procurement of the three Metop satellites; NOAA, for the exchange of instruments, data and operation cross-support; CNES, for the provision of IASI and ARGOS-DCS payloads;

Conclusions: EPS provides (1) Continuity to the current system; High level sounding performances: provide enhanced data streams needed to further improve the capabilities of advanced NWP systems; Multi-instrument capabilities: assure service beyond operational meteorology, e.g. climate research and monitoring); Instruments built on the heritage of Earth observation missions (GOME, ASCAT). These are introduced into an operational environment; Long mission duration (14 years). This will assure that users are provided with long-term near real-time and off-line data service for meteorological and climate applications Metop Payload, EPS Missions & Products

Programmatic Status Ground Segment Status: The Core Ground Segment (CGS) CDR held from late May to early July 2002 Core Ground Segment: Factory Acceptance Testing started for the Polar Station Facility (PSF), Front End Processor (FEP), Product Generation Facility (PGF), Flight Dynamics Facility (FDF) and the Dissemination Facility (DIF). Polar Site Infrastructure Service in Svalbard successfully completed its Verification Review in May 2002 Transportation, assembly and erection of both EPS antennas and radomes was completed by early August, within the available “weather window”. The RF, baseband and monitoring and control equipment shipped in autumn 2002 On-site Acceptance of the PSF planned for early 2003. Unified Archive Facility Detailed Design Review for the EPS extension took place in October 2002;
