Paper Abstract

This paper focuses on the simulation and experimental testing for the star sensor system about position accuracy with different spectrums. The simulated model has been presented to analyze the effect of stellar spectrums on star sensor. Stellar spectrum types of K0, A, F are chosen as simples and simulated with software CODE V. The simulated results show that the RMS position error of the image spot is 0.24 pixels. An experiment is taken to verify this effect. By setting different band-pass light filters in the optical path structure, different spectrums of star light are achieved. The image spot centroids have been obtained at five different angles of view when the simulated star light is in different wavelength range. The experimental results show that the RMS position error is about 0.18 pixels. It is similar to the theoretical simulation analysis.
