Abstract:

In its continuous development, the modern astrometry has reached an angular resolution of several microarcseconds. To take a full advantage of this fascinating achievement, we should change our method of defining and implementing celestial references frames. A new paradigm of the modern astrometry must be based on a consistent relativistic theory of space and time, i.e., either on general relativity or on its viable alternative, the scalar-tensor theory of gravity. This lecture discusses the basic premises of the relativistic theory of reference frames for space astrometry, and addresses mathematical links between these premises. We consider several applications of this theoretical machinery to the Space Interferometry Mission and to other astrometric satellites.
