For the analysis of radar altimeter data the precise knowledge of the satellite's ephemerides is an important prerequisite. For the ERS-2 satellite, launched April 21, 1995, the FRARE (Precise Range and Range Rate Equipment) system offers a new additional tool for the precise orbit determination besides the usual satellite laser ranges (SLR). In the following some POD tests are described. Although these tests are based on a preliminary set of the co-called revision 5 data, they clearly demonstrate the high quality of the data.
