Precision gravitational experiments using near-Earth satellites with onboard frequency standards during Doppler tracking of the trajectory of spacecraft are considered. Estimates of the magnitude of atmospheric interference when measuring the gravitational frequency shift for communication signals of a satellite with a ground-based tracking station are exemplified by the Radioastron mission. Algorithms for filtering gravitational effects against atmospheric noise are presented.
Key words: gravitational experiments, near-Earth satellites, algorithms for filtering, gravitational effect.
