船载USB瞬时站址残差异常情况分析

Exceptional Phenomenon Analysis of Instrumentation Ship's USB Residual Error

针对某航天发射任务测量船模拟演练快速评估发现的USB数据残差曲线异常情况,提出了测量船姿态测量视差修正原理分析、数据比对分析和试验验证相结合的分析排查方法,有效地解决了该问题。发现了导致该异常现象发生的视差修正模型中坐标位置参数航向修正错误问题,提出了视差修正的改进方法。

In a certain spaceship＇ s sinmlation drilling mission,it was found that the residual error of USB was exceptional. In view of this,an analytical method is proposed, which combines instrumentation ship attitude measurement parallax amend theory＂ analysis, data contrast analysis and experimentation validation. By em- ploying the method,it is demonstrated that the reason of exceptional residual error is the course amend inex- act among the parallax amend model. And the improved technique of parallax amend is provided to solve the problem effectively.
