| Abstract: | On the basis of the error spread law and the theory of position error in arbitrary direction of point，it is put forward and demonstrated that transverse position error equals to zero and longitudinal position error equals to the error of point position.Besides,error curve and error ellipse are analyzed.So, it is shown that error ellipse is inutility, and error curve is useful and effective. |
