None of the geodetic positioning techniques can achieve this goal alone. These goals were derived from the requirements of Earth science problems that are currently the international community's highest priority. 1 mm/y, with similar numbers for the scale (0. The Global Geodetic Observing System-GGOS, places very stringent requirements in the accuracy and stability of future realizations of the International Terrestrial Reference Frame (ITRF): an origin definition at 1 mm or better at epoch and a temporal stability on the order of 0.

Satellite altimetry from the 35 days repeat cycle mission of the ERS satellites and, especially, from the 10. Hence, the heights of the sea surface may be recovered very detailed. Satellite altimetry from the GEOSAT and the ERS- 1 geodetic missions provide altimeter data with a very dense coverage. The Cryosat-2 satellite have provided data along its 369 day near repeat since 2010 and as of May 2012 the Jason- 1 satellite has been o.Ī global high resolution mean sea surface from multi mission satellite altimetry Since the release of the Danish Technical University DTU10 global marine gravity field in 2010, the amount of geodetic mission altimetry data has nearly tripled. The impact of using jason- 1 and cryosat-2 geodetic mission altimetry for gravity field modelingĪndersen, Ole Baltazar Jain, Maulik Knudsen, Per
