The gravitational compass: Mapping of the gravitational field in General Relativity — •Dirk Puetzfeld — ZARM, Uni Bremen

In General Relativity, the comparison of clocks, as well as the measurement of the mutual accelerations between the constituents of a swarm of test bodies, is of direct operational significance. We show how a suitably prepared set of clocks and test bodies can be used to extract all components of the gravitational field. In particular, we comment on the role of the underlying reference frame in the determination of suitable clock and test body setups.
