This method is using GPS model to record the data ofGPS from mobile stations and static stations in six days. In every day the tmi e for location is from 9: 50 to 10 am. Then through seeking the average of every group of values ofmobile station and using the position difference by the values of static position to emend the value ofmobile station, the error of the value is reduced, and thus the value become more precise.
