The concept and causes of static drift in car GPS locators

　　GPS locator static drift refers to a certain error between GPS positioning and the actual location of an object, but it is consistent with the display of the actual route on the map, with only a certain interval. Static drift of GPS locators is only a temporary phenomenon that occasionally occurs in practical use. So, what are the reasons for static drift? Below is a detailed introduction for everyone.

　　1. Regarding the issue of GPS satellites, there is a propagation process that satellites encounter many factors after transmitting signals, such as errors with ground-based positioning devices. These factors are affected by weather conditions, such as clouds and covered objects, which can affect the accuracy of GPS positioning.

　　2. The GPS locator was not calibrated properly when it left the factory, which is considered a defective product, resulting in a fixed position deviation between the actual positioning and the map display. This situation should be paid special attention to at the beginning of use.

　　3. The CPU processing speed or algorithm of GPS locators is not of high quality, which results in less accurate data processing compared to detecting GPS signals when the car is moving at high speeds and when it is stopped, thereby affecting the positioning accuracy. It can be seen that purchasing original and reliable GPS locators is very important, and miscellaneous GPS locators should not be installed at will.
