Relativistic deviation equations and their application: Probing gravity with structured test bodies

在本项目中，我们能够为一个非常大的一类几何形状的偏差方程。此外，我们能够明确地表明，如何通过适当准备的测试物体和时钟来测量引力场。特别是，计算出了相对论重力和相对论大地测量的操作结果。这项提案中的新研究将涉及在称为"引力罗盘“的测量装置及其统一描述方面的进一步应用。随着项目的延长，我们希望在我们的研究结果的基础上进一步为我们打开这个有趣和重要的研究领域。

Within the present project we were able to work out deviation equations for a very large class of geometries. Furthermore, we were able to explicitly show, how the gravitational field can be measured by means of suitably prepared test bodies and clocks. In particular, operational consequences for relativistic gravity and relativistic geodesy were worked out. The new research in this proposal will deal with further applications in the context of a measuring device termed ``gravitational compass'' and its unified description. With this prolongation of the project we would like to further open up for us this interesting and important area of research on the basis of our findings.
