Abstract
The geopotential scale factor R 0 = GM/W 0 (GM — the adopted gravitational constant) and/or geoidal potential W 0 have been determined from the EGM96 geopotential model, the POCM 4B sea surface topography model and three years (1994–1996) of TOPEX POSEIDON (T/P) altimetry data: R 0 = (6 363 672.589 ±0.050) m; W 0 = (62 636 855.72 ±0.50) m2 s2. The 5 cm uncertainty in altimetry calibration limits the actual accuracy of the solution. However, the formal rms of R 0 is less than ±1mm which makes the monitoring W 0 and R 0 promising. Continuous W 0 /R 0 monitoring has been initiated in early 1997 and monthly values of W 0 and R 0 are presented and discussed.
