Abstract

Method and system for tracking between two communications participants of an optical satellite communications system to provide a communication connection between the two communications participants. The method includes transmitting a signal from a first of the two communications participants to a second of the two communications participants, in which the second communications participant includes a detector arrangement with a plurality of detectors in a common receiving plane. The method also includes acquiring a phase of the signal at each of the plurality of detectors and determining phase differences between the phases via a phase-processor, determining from the phase differences a phase angle of an alignment of the signal to the receiving plane, processing the phase angle with a tracking computer in order to align the receiving plane of the second communications participant with the signal, whereby the phase difference becomes zero, and continuously calibrating the plurality of detectors of the detector arrangement.
