摘　　要：用户星数据中继天线对中继卫星的跟踪规律研究是一个基本的、十分重要的问题。从工程应用角度研究了用户星数据中继天线对中继卫星的跟踪规律。首先对研究中涉及的坐标系进行了定义。基于开普勒轨道运动方程推导了一套数据中继天线跟踪中继卫星的角度及其变化角速度的数学模型。通过这套模型可以推算用户星跟踪数据中继卫星时中继天线转动的方位角和俯仰角的变化规律。最后通过仿真算例的结果分析验证了模型的正确性。Study on tracking law of data relay antenna for user satellite tracking TDRSS is a basic and very important problem. This problem was studied and resolved from the point of view of engineering application. Firstly, the related coordinate systems were defined. A set of mathematic models of tracking angles and these variation rates for data relay antenna tracking TDRSS were derived from Kepler equation of orbital motion. By using this set of model, the rotation azimuth angle, elevation angle and their change rates could be predicted. At last, the set of model was validated through the analysis of simulation results.
