Description: The channel of the angular automatic tracking of aircraft (А) is offered to direction (АTD) for the structure of the mobile multifunction laser informatively-measuring system that is intended for the use on a ground proof-of-concept complex. Basis of construction of steady channel is the use of frequency-temporal method of search, recognition and measuring of parameters of motion of А, optical-electronic module (televisional chamber and infra-red channel) and direct measuring of tangential speed (angulators) of А. Information about the angulators of А allows to compensate dynamic and fluctuation errors of filtration. Additional information about А from the wide-angle optical-electronic module allows to contain equally alarm direction on А, on condition of dramatic change of trajectory of his flight. Presented results of estimation of exactness descriptions of channel of АTD and chart - technical decisions of his construction. Exposed essence of increase of firmness of angular autoaccompaniment of А, goniometry of azimuth and place, realization of objective control and, if necessary, search of А, recognition and delivery of commands for his management.
