A Method for Measuring Gravitational Potential of Satellite’s Orbit Using Frequency Signal Transfer Technique between Satellites

We introduce an approach for the direct measurement of gravitational potential (GP) along trajectory a satellite, with specific focus on Low-Earth Orbit (LEO) satellites. A LEO satellite communicates several Geosynchronous Equatorial (GEO) satellites via frequency signal links. The GP difference can be measured in real-time using shift by equipping both and GEO precise atomic clocks. Since at high orbits precisely determined present field model EGM2008, satellite’s determined. In this study, simulation experiments were conducted, featuring GRACE-type as communication three equidistant results indicated that accuracy measurements primarily depends precision onboard Supposing optical clocks attain instability level 1×10−17τ−1/2 (τ seconds), we distribution covered trajectories 30-day observations. Then, centimeter based distribution. data derived from utilized to establish temporal fields, which have broad applications different disciplines.
