Compensation for Inter-satellite Relative Motion of Free-space Optical Communication
The relative motion of communication satellites which are not on a plane was analyzed.The acquisition probability and acquisition time was improved by compensated the point angles for terminal gimbal.And the charge coupled device target plane coordinates which decided by the receiving laser beam were modified to reduce the constraint for fast steer mirror.Numerical simulation resolving the relative motion model compensates the excursion to antenna rotation angles and charge coupled dirice coordinates.The curves show that the relative motion can be eliminated depending on compensation model analysis.The system structure was simplified that not needs to consider actuator cooperation with other device.That decreases the complexity of the whole system and saves energy.And numerical compensation method is convenient to realize for satellite computer program.
