This paper describes a new tracking and measuring control system for optical and electronic theodolite. This control system can provide automatic flying object tracking and measuring in visible and infrared band. It also can provide real-time output of the measured results. Use of the multi-mode measuring methods and the on axis tracking control technique can improve the stability of automatic tracking, tracking accuracy and the comprehensive tracking performance of the theodolite. At the same time the smooth switch over among several tracking modes can be carried out. New tracking techniques have been developed to deal with angular tracking rate that exceed one radian in both velocity and acceleration. At the present the tracking and measuring control system has been successfully applied in the optical and electronic theodolite. This paper covers the design concept for the on axis tracking control, the prediction, filtering and smoothing of target measurement, selection of bandwidth, the techniques of automatic video tracking using visible and infrared sensors and the architecture of the servo control algorithms.
