基于多模GNSS接收机的卫星系统完好性监测

Integrity Monitoring of Satellite Systems Based on Multi - Mode GNSS Receiver

为了满足多卫星系统完好性监测的需要,本文通过对比不同卫星系统定位结果的方法来监测各个卫星系统的可用性。利用上述方法对实测的三模(GPS、GLONASS和COMPASS)数据进行了处理,结果表明该方法具有可行性,可为多模GNSS接收机的自主完好性监测提供参考信息。

In order to monitor the integrity of different satellite navigation systems at the same time,the method of coordinate comparison is used.Through comparison of coordinates computed by different satellite navigation systems,the healthy status of satellite navigation system could be obtained.The result of processing observed data shows that the proposed method could be used to monitor the integrity of satellite navigation system.
