The error of the new test method is less than 10 by way of developing the new testing method, it has practical meaning to correct above errors for an airborne photoelectrical measurement system which cant aim in reversed position of telescope because of structural limit. Key words Photoelectrical theodolite; Air-borne photoelectrical measurement system; Sighting error; Non-perpendicularity between horizontal axis and vertical axis 0º() 180º() 2005021020050829 (1962 )() Email:
