Abstract：To analysis the error sources of app-based ride-hailing calculating mileage and time, 6 different scenes and 4 different app-based ride-hailing service platform calculating mileage and time data are tested in the microwave anechonic chamber environment. The results show that the timing error meets the stipulated requirements, on the highway, around the airport, due to the relatively good satellite signal, the mileage error is -0.4% to 1.6%, while in urban roads, railway stations and industrial parks, due to the interference of buildings and other environments, especially between urban roads, due to passing through the tunnel, with the disappearance of signals on some road sections, the mileage error is -0.4% to 5.5%. In high-speed auxiliary roads, the signal was not continuous, and the mileage error is 2.4% to 8.4%.
