The extended gravitational clock compass — •Gerald Neumann1, Guillermo Rubilar1, and Dirk Puetzfeld2 — 1Departamento de Física, Universidad de Concepción, Casilla 160-C, Concepción, Chile — 2University of Bremen, Center of Applied Space Technology and Microgravity (ZARM), 28359 Bremen, Germany
By extending the framework of the gravitational clock compass [1], we show how a suitably prepared set of clocks can be used to extract information about the gravitational field in the context of General Relativity. Conceptual differences between the extended and the standard clock compass are highlighted. Particular attention is paid to the influence of kinematical quantities on the measurement process and the setup of the compass. We also discuss the precision with which quantities as the acceleration and the angular velocity of the frame, as well as the components of the curvature of the spacetime, can be determined.
