Single-channel angel tracking receivers are widely applied in tracking systems of data relay satellites. Based on the practical working processes of angle tracking receivers, the necessity of evaluating the angle mea- surement accuracy in dynamic tracking processes is discussed, and a method is proposed to evaluate the angle measurement accuracy in dynamic tracking processes. Based on a practical group of parameters, a case study on dynamic tracking process of a single-channel angel tracking receiver is provided. In the case study, the evalua- tion steps of angle measurement accuracy in dynamic tracking processes are demonstrated. The relationship be- tween angel measurement accuracy and averaging time is investigated, and the angle measurement accuracy in dynamic tracking processes and static tracking processes are compared as well.
