Simulation Research to the Navigation Signal Error of BDS Satellite

摘要：

　　In order to realize the detection and diagnosis of satellite navigation receiver in environments such as indoor,underground,trench,forest,urban building and mountain where there are little or no satellites,it is necessary to simulate the BDS satellite navigation signal,the difficulty lies in the simulation of the error signal of satellite navigation system.The paper analyzes the signal simulation principle of BDS satellite,researches several error source models of satellite signal including satellite clock error,ephemeris error,relativistic effects,influence of earths rotation,radiowave refractive error and multipath error and proposes the method to calculate the error during BDS satellite signal simulation,thus providing the approach for the accurate simulation of BDS satellite navigation signal.
