摘要
阐述广域实时精密定位系统完好性监测系统的设计原理,利用两路数据设计了一种的完好性反向监测方案。方案可以在不减少数据源参考站的情况下拥有充足的完好性监测站,从而使系统在保证差分产品精度的同时获得更大的完好性监测区域。同时对完好性监测的关键技术进行了阐述,说明了差分产品监测、定位外符合监测、内符合精度估计、卫星钟状态等完好性监测的内容及方法。
The design principle of monitoring system of wide-area real-time precision positioning system is described and a new integrity monitoring scheme is design by using two-way date. The new scheme has sufficient integrity monitoring stations while the data source reference station can not be reduced, so that the system can have bigger integrity monitoring area and in the same time, guarante the accuracy of differential product. In addition the key technique of integrity monitoring is expounded, including the differential product monitoring, external position coincidence monitoring, estinate of internal coincidence, state of satellite clock, etc.
