The GPS mode can’t be fixed. It keeps drifting. What’s the reason?

Answer:

1. If it is winding, the magnetic compass is out of shape.

2. If it is irregular, the magnetic compass may be disturbed.

3. If it is within a certain range, such as 5 meters, drifting back and forth within 10 meters, the GPS signal is not good, or the GPS is interfered。
