Abstract：This paper collects dynamic data from low-cost receivers in three different speed ranges and analyzes the data reception capability, data quality, and navigation positioning performance of multi-system interoperable signals, B1C/L1/E1, and B2a/L5/E5a, within various speed intervals. The results show: 1) As the speed increases, the reception capability of interoperable signals gradually deteriorates. BDS-3 can maintain visibility of more than nine satellites on average. Among the interoperable signals, B1C/L1/E1 exhibits superior data integrity but is more susceptible to data interruptions.2) As the speed increases, the carrier-to-noise ratio of interoperable signals decreases, and cycle slip ration increase. However, the pseudo-range noise, carrier phase noise, and multipath effects are less affected by speed. Notably, B1C/L1/E1 exhibits minimal carrier phase noise and multipath effects. 3) The influence of carrier speed on positioning accuracy has no obvious regularity. The speed and the degree of environmental occlusion affect the positioning accuracy. The multi-system interoperability signals combination positioning has more improvement than the single system positioning performance; BDS-3 has high accuracy in the middle and low speed range, and its precision of PPP is better than other systems by more than 17%.
