Paper Abstract

The SILEX project is an experimental communication system aimed at demonstrating, in orbit, the feasibility of intersatellite optical communications using semiconductor lasers. As part of this project we have developed a precision mechanism to point the transmitted beam ahead of the current receiving satellite position. This is necessary due to the relative motion of the satellites, the narrow beam and the finite velocity of light. The design and construction of a prototype of this device is discussed along with measurements of performance. The technique as described can be used in many applications requiring precision beam stearing or rotation control.
