　　1. GPS satellites, satellite signal propagation process and ground receiving equipment will all produce errors in GPS measurement. Or affected by some weather, the accuracy of GPS positioning will also be affected when there is a covered house.

　　2. The GPS car locator is not calibrated well when leaving the factory, resulting in a fixed position offset between the actual positioning and the map display.

　　3. The processing speed of the GPS car locator CPU or the GPS algorithm is not good enough, resulting in a period of "drift" when the GPS device detects the GPS signal when it is moving at a high speed and the data when it stops, thus affecting the positioning accuracy.

　　4. In general, the faster the speed, the more obvious the "drift". At the same time, the accuracy of GPS positioning is also affected by time, location, weather conditions and many other aspects.
