Abstract

An automatic tracking theodolite which provides the angular co-ordinates of an object which is in contrast on an ambient back ground, has a T.V. camera (1), a rotatable support which can be positioned about two intersecting axes and on which the camera is mounted, two motors associated with the support, a T.V. monitor linked to the camera and a synchronisation clock which provides temporal reference signals which control the electronic scanning of the camera.
