AUTONOMOUS ASTRONOMICAL SYSTEM FOR NAVIGATION AND TRACKING
Annotation
An autonomous astronomical system for artificial satellite navigation and orientation is presented. The system makes use of “satellite–star” angle measurements with optical-electronic instruments. A reciprocal angles method and a tracking method are developed to solve the navigation problem. In both the methods, the line-of-sight direction is calculated from obtained estimates of the satellite orientation. Along with generation of high-precision navigation data on the satellite under observation, the tracking method reveals the facts of the satellite orbit change (maneuver) even under weak pulse (1—3 m/s). Results of simulation testing of the developed methods are presented.
