Application of Star Map Simulation Method in Study of Star Sensor Technologies

tar sensor is an attitude-measuring instrument with high accuracy.Star map simulation with the aid of computer can offer abundant star image data.Firstly,the principle and methods are discussed of simulating the imaging of star sensors and producing simulated star maps,w hich are realized by the extended programming on optical design softw are.Then,programming design results of star map simulation are given together w ith the applications of star map simulation method in optical system evaluation,star image extraction algorithm and star identification algorithm,and calibrating system errors.The study proves that star map simulation serves as an important support to the study of star sensor technology.
