Present and future GNSS applications to oceanography and geodesy

This presentation will summarise GNSS applications to oceanography and geodesy, including real time positioning of altimetric satellites; use of reflected GNSS signals as bistatic altimetry; new developments in altimetry e.g. wide swathe; GNSS applications to dedicated gravity field missions GRACE and GOCE; GNSS for reference frame issues and geodetic research and developments towards real-time GNSS orbits etc.
