Ten altimeter missions in Low Earth Orbit (LEO) are currently in-flight, with the last satellite of this impressive LEO altimetry constellation, SWOT, successfully launched in December 2022. This brand new satellite already provides first observations of water bodies with unprecedented details thanks to his Ka-band Radar Interferometer (KaRIn). The Precision Orbit Ephemerides (POE) of the past and present altimeter missions for use on the science-quality Geophysical Data Record (GDR) are consistently processed in the CNES POE-F Standards.
This paper focuses on the Sentinel-6 MF reference mission and the preliminary orbits processed with the new CNES POE-G Standards. A comparison of the performances of this updated set of orbits with the current POE-F solutions will be shown. More information on the Standard evolutions concerning the measurement and dynamic models will be provided.
