船载测角设备实时数据处理算法研究

船载测量设备布站灵活,在实时数据处理中采用船载测角设备与固定站测角设备实交会可以获得更好的交会角度,提高精度。针对测量船位置及姿态实时变化的特点,分析了船载设备的相对位置关系,推导了坐标转换方法,将船载测角设备经转换后等同视为一位置可测的固定站设备,与其他固定站测量数据进行交会处理,经过模拟试验结果分析,证明本算法精度满足要求,为圆满完成试验任务提供了保障。

A study on real-time data processing arithmetic of shipborne angle measure equipment

Based on the flexible allocation characteristics of the shipborne measure equipment,the angle intersection is adopted with shipborne and fixed-site angle measure equipment in the real-time data processing.We can gain better measure angle and improved precision through the method.The relative position of shipborne equipments is analyzed aiming at the real-time change position and attitude of ship.After coordinate transformation,the data of shipborne measure equipment is calculated as measurable fixed-site data.The result of simulation shows that the arithmetic can meet accuracy requirement and guarantee test mission.
