The located aiming mechanism at the muzzle and located adjustment mechanism at the breech are designed in the system. Besides those, the system also uses an autocollimator with accuracy of 1″ and a collimating mirror together to determine the axis of the datum tube. An electronic level with accuracy of 2″ is employed to measure and display the value of the included angle and the parameter of the inclined direction. The entire accuracy of this system is σ≤±9.1″. This paper describes the composition and the operating principle of the system and analyzes the accuracy. The development of this system supplies reliable measurement method for new rocket artilleries and artilleries, and this technology is of a good application prospect.展开更多
