A jitter rejection technique in a satellite-based laser communication system

Abstract

A technique, resulting in the significant reduction of negative effects of satellite jitter on the accuracy of laser beam positioning in communication systems, is presented. It implies application of vibration monitoring instrumentation for estimation of the motion components constituting jitter. A self-tuning feedforward jitter compensation scheme is introduced to the existing mirror positioning control systems. The technique is verified by computer simulation and is in the process of experimental investigation.<>
