Abstract

A method of compensating the satellite vibrations in intersatellite laser links was presented. The satellite vibrations were detected by a CCD instead of the traditional angular sensors, so the tracking system was simplified. The angular errors from the satellite vibrations influence the beam tracking, while these errors can be well compensated by a feedforward control system. An experimental study on the vibration compensation technology was performed, and a vibration simulation device and a feedforward compensation system were built in the lab. Using a CCD with the sampling frequency of 1 kHz, tracking errors can be reduced by 71% after vibration compensation when the frequency of angular vibrations is 100 Hz.
