Abstract
In December 1980, the Air Force Space Division Lasercom office completed field evaluation of 1 Gbps space laser communications system in an air-to-ground flight test program at White Sands Missile Range, New Mexico. A ground-based brassboard receiver terminal performed the functions of acquisition and tracking, beacon beam pointing, optical data reception at 1 Gbps, and optical data transmission at 20 kbps. The ground terminal is described from an acquisition and tracking viewpoint. The design of fast-steering pointing and tracking inner loops coupled with slower gimbal outer loops is discussed. Results of the recent field evaluation in terms of acquisition times and tracking accuracy are presented.
