Orbit determination for radar altimetry satellites

Satellite radar altimetry is one of the primary tools to study sea level changes. It allows measuring sea level heights and variations globally at various time scales. Precise orbits of altimetry satellites are a prerequisite for the analysis of altimetry measurements. The list of the major altimetry missions includes past missions GEOSAT (1985-1990), ERS-1 (1991-1996), TOPEX/Poseidon (1992-2005), and GFO (1998-2008), and the current missions ERS-2 (since 1995), Jason-1 (since 2001), ENVISAT (since 2002), Jason-2 (since 2008), and Cryosat-2 (since 2010).

REAL-GOCE

REAL-GOCE (REal data AnaLysis GOCE) was a joint project of several German Research Institutes, namely the Rheinische Friedrich-Wilhelms-Universität Bonn, The Bundesamt für Kartographie und Geodäsie Frankfurt, Universität Hamburg, Deutsche Geodätisches Forschungsinstitut München, Technische Universität München, Universität Karlsruhe, Universität Stuttgart and Deutsches GeoForschungsZentrum Potsdam. The REAL-GOCE project was funded by the German Federal Ministry of Education and Research (BMBF) within its Geotechnologien Key Research Area "Observation of System Earth from Space III". The funding period for REAL-GOCE ended mid of 2012.
