Altimetry Rank Deficiency in Crossover AdjustmentIn altimetric measurements we observe the height of a satellite on the actual sea surface ( H. ). This quantity (see Fig. 1) can be modelled as:.where h is the satellite’s height referred to the ellipsoid, N is the geoid, ζ the sea surface topography, splitted into stationary component ( ζ. ) and time dependent component ( ζ. ) and . is the noise.

The 30’ mean anomalies were estimated from terrestrial gravity data, from altimeter derived anomalies, from 1° × 1° anomalies when such data was available. For areas devoid of gravit

It will consist of a satellite-only model derived purely from satellite tracking data and a combination solution additionaly incorporating Earth surface gravity data and altimeter data..At present a preliminary solution (PEGM78) has been accomplished, having the following chara

Evolution Strategies and Other Methodswing designations are accepted: fM = geocentric gravitational constant; R = equatorial Earth’s radius; r, ϑ, λ = radius-vector, polar angle and longitude of a point of external space; . = fully normalized adjoint Legendre functions. The fully normalized coefficients . are practically represented by
