In order to analyze the influence of solar panels on the propagation of navigation signals,simulation analysis and ground far-field measurement campaign in the proving field were carried out.In this paper,the propagation of RNSS signal when solar panels rotated by different angles was simulated using the moment method.The effect of multipath caused by solar panels on the ranging errors was also studied.
