High accuracy fine-pointing system - Breadboard performances and results
Abstract
A fine pointing system designed according to the requirements of the Semiconductor Laser Intersatellite Link Experiment 1989 (SILEX 1989) is described, with particular attention given to the synthesis of the final breadboarding. The study includes all the pointing functions where the pointing, acquisition, and tracking (PAT) functions are associated with different FOVs. The laboratory model consists of a complete pointing system with two CCD sensors for detection, two general-scanning single-axis actuators, and the overall control electronics. Each major PAT function of the laboratory model was separately tested, giving all the major impacts for the future PAT applications concerning mechanical margins, optical aberrations, sensor linearity, and servoloop communications.
