Analysis and Simulation of Multipath Error for Satellite Navigation Signals

Multipath error is an important error source in the tracking measurement of the navigation signals, and the multipath analysis is also significant to the signal system designing and signal optimizing. The multipath error envelope curve and average multipath error based on non-coherent EMLP (Early Minus Late Power) are usually used to measure the multipath rejection ability of the navigation signals. Now, the signal parameters of COMPASS satellite navigation system have been published. The method and principle to analyzing multipath error are given in this paper, the multipath performance of different signals adopted by COMPASS system is analyzed, and the simulation results are given. The analysis results in this paper can offer the research basic and reference to the system designing of the satellite navigation in our country.
