Method and system for tracking two communication subscribers of an optical satellite - communication system

摘要

A method for tracking two communication subscribers of an optical satellite - communication system, in particular of a satellite, as well as a ground station, for providing a communication connection between the two communication participants, in which:– a first input of the two communication subscriber is a signal (15) to a second of the two communication participants transmits;– the second communication subscriber is a detector arrangement having a plurality of detectors (12, 13, 19) in a common reception plane 22 through which in each case the phase of the signal (15) is detected, wherein by means of a phases processing means phase differences between the phases are determined;– from the phase differences a phase error angle (18) of the alignment of the signal (15) to the reception plane (22) is determined;– the error angle (18) by means of a according to the linkage means 17-20 could computer is processed, in order to the receiver unit of the respective communication subscriber to align the signal (15), so that the phase difference becomes zero;characterized in thatthe detectors (12, 13, 19) of the detector arrangement continuously, to be calibrated, wherein for the calibration by means of a calibration signal between the signal delays..
