Abstract:The satellite navigation signal performance evaluation is the main part of satellite navigation system performance evaluation. Indexes of the satellite navigation system performance related signal including the first positioning time, static positioning accuracy, the receiving sensitivity, anti multipath performance, anti disturbance performance, compatibility and interoperability. Based on the analysis of the relationship between performance of satellite navigation system and navigation signal, this article establishes the related indicators signal performance evaluation model, and analyses error sources of signal performance, puts forward a comprehensive evaluation method of a signal. The simulation through the selection of satellite navigation civil signal, proved the applicability of this method, can provide effective AIDS to navigation signal design and signal receiving technology development.
