With the rapid development of the global navigation satellite system (GNSS), to build the corresponding GNSS monitoring and evaluation system, has a great realistic significance to the operation condition of the BDS satellite navigation system and various performance indicators for monitoring and evaluation. At present, the International GNSS Monitoring And Assessment Service (iGMAS) launched by China in the world is building in an orderly way. This article direct at GNSS navigation space signal, use the four system’s precise ephemeris data and hybrid broadcast ephemeris data from January to October in 2014 to calculate and analysis; Direct at the characteristics of single and mixed constellation, derivation the calculation formula of the SISURE (Signal-in-Space User Range Error); Do statistical analysis and accuracy evaluation to the broadcast ephemeris data based on the four system precise ephemeris data. The calculation results and analysis shows that: the SISURE accuracy of the four systems by broadcast ephemeris is better than 2.5 m.
