GPS射频干扰浅析

Analysis On the Influence of RFI On GPS Reception

摘要:

论述信号噪声比和信号噪声密度比的概念，分析了射频干扰(RFI)对GPS接收的影响，最后说明了直接检测RFI的方法以及RFI源的定位。

Abstract:

Operation of GPS receiver is dependent upon the external radio frequency signal, and therefore is liable to be affected by radio frequency interference (RFI). It is possible that the RFI results in navigation accuracy degradation or receiver tracking loss
