船载卫通站天线控制单元引导计算异常的解决

Solution to Abnormal Calculation Problem of Antenna Control Unit in Shipboard Satellite Communication Station

某船载卫通站天线控制单元(ACU)在一次任务海域使用捷联惯导(SINS)作为数据源引导计算时出现了卫星捕获异常情况。针对该问题,从分析船载卫通站卫星捕获原理入手,详细比对了各类引导源的数据格式与异同点,结合以往工程经验进行问题排查定位,提出了相应的解决方案并完成了ACU软件的修改完善和测试验证。试验结果表明,采用所提方法,问题定位准确,解决方案简单有效、可行性强,可为类似问题的解决提供参考。

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.
