Studying the Evolution of Resolution Capabilities and Approximation Accuracy of Global Models by Spectral Characteristics

Abstract The paper presents research of the evolution resolution capabilities and approximation accuracy last decade global geopotential models based on space gravimetric measurements CHAMP, GRACE GOCE missions using their spectral characteristics. comparison between model data with point gravity anomalies quasigeoid heights for territory Novosibirsk region is shown. Based results conclusion was drawn that characteristics current under test built by satellite gravimetry do not achieve specified 1 cm mGal investigation. has made it possible to state at technological methodical level potential been reached as concerns EGF enhancement.
