In project C02, we develop the conceptual framework of general relativistic geodesy. We generalize geodetic notions and redefine central ideas within the theory of General Relativity, which we then link to established definitions in the (post-)Newtonian limit. With regard to contemporary and future high-precision measurements, we analyse the description and decomposition of the relativistic gravitational field as well as relativistic effects on satellite orbits, signal propagation, and the redshift between clocks on Earth and in space. We investigate the novel concept of satellite swarms with clocks as a potential new data channel for combined gravity field solutions.

在项目C02中，我们发展了广义相对论大地测量的概念框架。我们概括了大地测量的概念，并重新定义广义相对论中的中心思想，然后我们将其与（后）牛顿极限中的既定定义联系起来。关于当代和未来的高精度测量，我们分析了相对论引力场的描述和分解，以及相对论效应对卫星轨道，信号传播，地球和空间时钟之间的红移。我们调查的新概念的卫星群与时钟作为一个潜在的新的数据通道组合重力场的解决方案。
