Characteristic Analysis of Computing Other Gravity Quantities by Vertical Deflection of Satellite Altimetry
摘要
Abstract
Vertical deflection is widely used in determiting marine gravity field in satellite altimetry,when regarded as derived quantity.The formulae computing geoidal height,gravity anomaly and gravity disturbance by vertical deflection are given according to the definition of the boundary problem of physical geodesy in condition of spherical surface.The effects of depressing vertical deflection error are analysed in different integral formulae.The variety features of the kernel function are also discussed.The chief conclusions are given that the availability and stability of computing geoidal height is priority to that of computing gravity anormaly or gravity disturbance using sea surface grid vertical deflection in satellite altimetry.关键词
