On relativistic geodesy and orbit deviations — •Dennis Philipp¹, Claus Laemmerzahl^1,2, Volker Perlick¹, and Dirk Puetzfeld¹ — ¹ZARM, University of Bremen, Bremen, Germany — ²University of Oldenburg, Oldenburg, Germany

For metrology, geodesy and gravimetry in space, satellite based instruments and measurement techniques are used and the orbits of the satellites as well as possible deviations between nearby ones are of central interest. The measurement of this deviation itself gives insight into the underlying structure of the spacetime geometry, which is curved and therefore described by the theory of general relativity. We investigate the deviation of nearby orbits that can be modeled using the relativistic deviation equation (Jacobi equation for first order deviations) and we comment on the applicability and physical effects that can be described within this framework.
