Engineering methods to improve the accuracy of digital guidance in trajectory tracking

In the process of aircraft test, the center computer needs to send digital guidance information to the TT&C equipment in real-time, so that the TT&C equipment can catch the target in time and track it stably. In this paper, the digital guidance algorithm for real time data processing of trajectory tracking is introduced, the main reasons influencing the digital guidance precision are analyzed, and the data refinement processing method based on trajectory fusion and the multi-stage combined filtering method are proposed, which can effectively improve the digital guidance accuracy for TT&C equipment and has high practical application value.
