General Relativity and Astrometry — •Sergei Klioner — Lohrmann-Observatorium, TU Dresden

Unprecedented accuracy expected from space astrometry projects makes it indispensable to formulate the models of observational data in the framework of General Relativity. Without proper use of General Relativity it would impossible to extract any sensitive physical information from observational data. Moreover, a high level of consistency between various parts of data processing chain is required. In this way, General Relativity becomes an applied discipline with many standard applications at the engineering level. On the other hand, the effects entering the relativistic models can be used to test the theory of relativity. An example of the ESA space astrometry mission Gaia will be used to illustrate high-accuracy relativistic data modeling. A suite of relativistic tests with astrometric data will also be discussed.
