In the view of future developments in the field of high-accuracy astrometry it is important to understand how relativistic models of light propagation can reach the accuracy of 1 nanoarcsecond. First steps towards a consistent general-relativistic theory of light propagation with an accuracy of 1 nanoarcsecond will be done. A theory of light propagation in the gravitational field of moving bodies of arbitrary shape and structure will be formulated in the first post-Minkowskian approximation. The post-post-Minkowskian effects will be assessed and, at least partially, investigated.

从高精度天体测量领域的未来发展来看，重要的是要了解光传播的相对论模型如何达到1纳弧秒的精度。我们将迈出第一步，建立一个精度为1纳弧秒的一致的广义相对论光传播理论。光在任意形状和结构的运动物体的引力场中的传播理论将在第一个后Minkowskian近似中得到表述。将对后明科夫斯基时代的影响进行评估，至少部分进行调查。
