Looking at the track on the positioning platform, I find that the driving track of the gps car tracker magnetic is very different from the actual situation. The original situation in the gps industry is called - drift.

How does drift happen?

1, the GPS device is not calibrated properly at the factory, resulting in a position offset between the actual positioning and the map display;

2, the processing speed of the CPU or the GPS algorithm is not good enough, resulting in a "drift" phenomenon when the GPS device detects the GPS signal at high speed and the data when it stops;

3, the installation environment is affected, the installation position should not be too closed, do not have metal objects. The occasional jump point, drift is normal, under the current technical conditions, most GPS products have this phenomenon.

4, the GPS signal will be affected by bad weather and then drift.

5. Influence of geographical environment where gps car tracker magnetic field is located. Such as underground parking garage, tunnel, alley, high-rise, magnetic field and other environments.
