| Abstract: | The geopotential scale factor Ro= GM/Wo(the GM geocentric gravitational constant adopted) and/or geoidal potential Wo have been determined on the basis of the first year's (Oct 92 – Dec 93) ERS-1/TOPEX/POSEIDON altimeter data and of the POCM 4B sea surface topography model: Ro°=(6 363 672.58°±0.05) m, Wo°=(62 636 855.8°±0.05)m2s–2. The 2°–°3 cm uncertainty in the altimeter calibration limits the actual accuracy of the solution. Monitoring dWo/dt has been projected. |
