According to the error control simplex the geometric characters of the measurement point set of error control are analyzed.Through the confidence interval the determination method of the model set in the range of error control simplex is proposed.The error correcting method of GPS measurement control grid is given through geometric characters of error distribution and EMD.Experiments show that the method can realize the exact positioning in the range of less than 33cm through about 200 measurement points for the error between-15 m to +15 m in GPS triangle measurement control grid.
