COORDINATOR Russian patent published in 2014 - IPC G01S3/78 

FIELD: physics, navigation.

SUBSTANCE: invention is intended for use in direction-finding means and control devices. A coordinator comprises, mounted on an optical axis, a receiving lens, an image analyser with a holder having a through-hole, a condenser, a four-element quadrant photodetector, a light-emitting diode, a photodiode, an actuating motor, a coordinate determining unit, wherein the image analyser and condenser are integrated into a single optical unit in the form of two lenses, the connection plane of which lies in the focal plane of the receiving lens, and the inner surface of one of the lenses is coated with a coating which is non-transparent in the visible and infrared range; the coordinator also comprises a frame clock pulse former, three delay lines, four power supplies, an optical-mechanical angular position sensor mounted on the axis of a reducing gear. The listed devices are designed and connected to each other in a certain manner.

EFFECT: high accuracy of determining coordinates.
