Abstract

Simulation of star tracker system. It deals with questions of projecting an observed area of a star sky is described. Calculation of an optical signal on a surface of an opto-electronic device, coming from a star with a random visible magnitude is made. Transformation of optical signal to electric and processes of recognition of observed group of stars are imitated, with the aim of calculating spacecraft orientation.
