| Abstract: |
| The problem occured that the antenna failed to track the satellite when antenna control unit(ACU) of shipboard satellite communication station used strapdown inertial navigation system(SINS) data source in a certain sea area.For this problem,this paper starts with analyzing the tracking principle of shipboard satellite station，compares the characteristics of each data source in detail，locates and detects the problem according to experience in engineering，proposes the corresponding solution and completes ACU software modification and test. The experiment results illustrate that the problem is located accurately，the solution is simple，effective and feasible,which can help to solve similar problems. |
| Key words: shipboard satellite communication station antenna control unit data source strapdown inertial navigation system leading calculation |
