Geoid Recovery at 0.5 Degree Resolution from Global Satellite Gradiometry Data Setsllite gravity gradiometry (and similar) data..A global buried masses grid is obtained as an intermediate solution, from which geoid undulations, gravity disturbance components and disturbing gravity gradient components can be regenerated by direct use of Newton-type formulae..Test computations using

Compact Approximation of the Geoid Height on the Base of Modified High Resolution Global Geopotentiawing 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

Review of Geoid Prediction Methods in Mountainous Regionsation surface, thus requiring the use of Molodensky’s theory instead of Stokes’ theory. For practical computations, Molodensky’s equations, as well as Stokes’ equation, may be reformulated as convolution integrals that can be efficiently evaluated by Fast Fourier Transform (FFT) techniques.

The Determination of Oceanic Geoid Using Modified Hotine Integralon of oceanic geoid..In order to derive more accurate geoid undulation, the approach method, analogous to Molodensky procedure, is introduced to Hotine integral. Both the error analyses and computational results indicate that the application of approximate function H(.. ) has obviously quickened the

A Strategy for Gross-Error Detection in Satellite Altimeter Data Applied in the Baltic-Sea Area for astal areas are the data contaminated by gross-errors and by biasses and tilts which have not been eliminated due to the missing cross-over with other tracks..Using least-squares collocation (LSC) with altimeter track biases and tilts as additional unknowns it is possible to compute adjusted altimet
