GPS设备海上动态定位精度检测新方法

摘要

In order to solve the dynamic positioning accuracy testing of maritime GPS equipment, a method al u-sing high-precision total station to track satellite positioning equipment dynamicly for dynamic positioning accuracy assessment was proposed. The testing baseline data collection and processing, and converting the GPS positioning data to test benchmark, by use of attitude data provided by inertial navigation equipment, were discussed. Furthermore, the system error was analyzed. Finally, the experiment result showed that the new method was effctive.%为解决GPS设备海上动态定位精度检测的问题,提出了利用高精度全站仪对GPS设备动态跟踪进行动态定位精度评定.阐述了检测基准数据的采集和处理,以及利用惯性测量设备提供的姿态数据将GPS定位数据归算到检测基准.简要介绍了进行动态定位精度评定所采用的方法,并对系统的误差进行了分析.最后通过实验验证了新方法的有效性.
