Abstract: [eng] [cze]
A continuous progress in the Earth gravity field modeling requires some refinements in their accuracy assessments. The method based on latitude lumped coefficients, which makes use of satellite crossover altimetry data (independent of the tested gravity models) has been developed in years 1992 - 2000. It was applied on various gravity models, recently on EIGEN IS, which already includes data from the CHAMP mission. For the first time, EIGEN IS model has degree-dependent calibration factors and we tested and confirm that their choice is a right one. Přehled metod testování přesnosti v současné době publikovaných modelů tíhového pole Země pomocí diferenciální altimetrie s křížícími se body pro jednu a dvě družice.
