Abstract:

Research is reported on the study and investigation of acquisition and tracking for two hypothetical, optical, space-communication links. This effort was directed toward establishing requirements and developing the analytic tools necessary for this study. The specific items investigated were the regions of acquisition and tracking, probability density functions for acquisition regions, target loss-rate, closed loop analysis of gyro-stabilized tracker, and tracker stabilization. The specific regions of acquisition are given for the earth and moon satellites. Mathematical expressions for determing probability densities for acquisition are given. Target loss-rate is given in terms of tracking system parameters. An analysis of the closedloop performance of a gyro-stabilized tracker also is given. Equations were developed showing the interaction of torques between trackers stabilized by various techniques and the vehicle. Expressions were also developed for determining allowable deflections of the vehicle and tracker due to those torques. Author
