Breadboarding of a high bandwidth acquisition and fine tracking system for satellite optical communications
Abstract
A breadboard representative of an actual European optical intersatellite link (ISL) has been built to verify the critical submicroradian pointing accuracy required for an ISL at 0.8 micron. This paper describes the breadboard, the test bench, and experimental results on acquisition and tracking. Pointing loop feasibility based on CCD detection is demonstrated, and computational results measured in step response time, accuracy, and rejection are verified. A high 800 Hz bandwidth is obtained, and bandwidth bottlenecks are identified.
