The invention relates to a method for moving a differential base station based on a global positioning system (GPS)/inertial navigation system (INS)/assisted global positioning system (AGPS), and belongs to the technical field of vehicle navigation and positioning, which comprises the following steps of: mounting a GPS/INS/AGPS combined navigation system on each of partial vehicles; obtaining vehicle position information of each of the vehicles through the combined navigation system; computing the position information with satellite position information obtained by the AGPS, to obtain an actual distance between each of the vehicles and each of observed satellites; comparing the actual distance with a satellite pseudo-range measured by a GPS receiver, to obtain a pseudo-range correction value of each of the observed satellites; broadcasting the satellite pseudo-range correction value to other vehicles just loaded with normal GPS receivers, subtracting the received satellite pseudo-range correction value on the
