FIELD: star navigation tracking systems.
SUBSTANCE: invention can be used in tracking systems designed for star navigation. The optical-electronic tracking device contains a biaxial cardan suspension with electric drives and angle sensors, a focusing lens installed in it, consisting of a first aspherical concave mirror with a central hole installed in series along the beams and a second mirror, an image transfer system and a photodetector, as well as series-connected with a photodetector, a video signal processing unit, a calculation unit configured to be connected to the on-board information system and to which signals from angle sensors are received, and a control unit, the signals from which are fed to the gimbals electric drives. In the focusing lens, the second mirror is made convex, the image transfer system is made specular and consists of a first aspherical concave mirror with a central hole and a second convex mirror with a central hole installed in series along the beams, installed near the plane of the intermediate image. The ratios specified in the claims are fulfilled.
EFFECT: increasing the probability of detecting dim stars by reducing the background radiation and increasing the focal length while ensuring its compactness.
