Method and system for processing GPS drift

The present application relates to GPS positioning and discloses a method and system for processing a GPS drift. The method comprises a step of determining the expected error information of the position deviation rectification of the equipment in an area, a step of obtaining the GPS initial position and the position after the position deviation rectification of the equipment in the area and, and a step of determining the GPS drift of the area according to the expected error information, the GPS initial position and position after the position deviation rectification of at least one equipment in the area. Through the method and the system of the invention, the GPS drift can be effectively improved.
