Theoretical aspects of relativistic geodesy — •Dennis Philipp — ZARM, Universität Bremen

General Relativity is at present the best available theory of gravity, as its predictions have been verified by all previously conducted experiments and observations. The technological capabilities for gravitational measurements on Earth and in its vicinity recently improved dramatically. Therefore, relativistic effects become increasingly important in modern relativistic geodesy. Although at present usually the first order post-Newtonian approximation of GR is sufficient, this may not be correct for specific applications and for future and contemporary high-precision geodetic measurements. We review results for high-precision relativistic orbit modeling, the analytic description of the (gravitational) redshift between satellites and Earth-bound clocks, relativistic leveling, and the definition of the relativistic geoid. In addition, we outline how methods and concepts from relativistic geodesy can be applied to astrophysics of compact objects and vice versa.
