This study reports on the absolute and cross calibrations of the Jason-1 and ENVISAT altimeters launched in December 2001 and March 2002 respectively. The ENVISAT study has been undertaken as a contribution to the ENVISAT alimeter Cross Calibration and Validation Tam and the Precise Orvit Determination Team. Cross calibration of ENVISAT utilies both repeat pass data with ERS-2 and crossover data with ERS-2, TOPEX.Poseidon and Jason-1. Values from ENVISAT relative calibrations using geophysical data from the ENVISAT GDR's will be compared against results utilising orbits and other corrections computed at Newcastle University. In addition results will be presented from an absolute calibration campaign for the TOPEX, Poseidon and Jason-1 altimeters utilising UK tide gauge data extrapolated to sub-satellite points using local models for the geoid with the ocean tital corrections inferred from the TOPEX altimetry.
