Abstrakt EN: Integral transformations of the disturbing potential derived from satellite altimetry onto satellite-to-satellite tracking data are formulated, investigated and applied in this contribution. First, corresponding differential operators, that relate the disturbing potential to the disturbing potential differences and the line-of-sight gravity disturbances, are applied to the spherical Abel-Poisson integral. This yields two integral transformations for which respective kernel functions are given in both spectral and spatial forms. Second, truncation error formulas for both integral transformations are provided in the spectral form. Also expressions for the corresponding truncation error coefficients are provided. Third, practical estimators for evaluation of the disturbing potential differences and the line-of-sight gravity disturbances are formulated, and their correctness and expected accuracy are investigated. In particular, we investigate the error propagation through truncated integration, and the omission and commission errors, which are related to the evaluation of the distant zones, for the GRACE satellite mission.
