Paper Abstract

Star sensors achieve very accurate attitudes for space vehicles by comparing observed stars in their field of view with the cataloged guide stars. Guide star selection is a key work during the star sensor designing. Infrared star sensor provides accuracy navigation information to air vehicles which fly near the ground in the atmosphere. According to working characteristics of the infrared star sensors, 2MASS(Two Micron All Sky Survey) star catalog is adopted as the raw star source. On the basis of analyzing its data structure, the scheme of selecting binary stars as guide stars and calculating their equivalent magnitudes and positions is discussed. The procedures to select the guide stars are described completely by processing 2MASS. The guide star catalog for infrared star sensors is established. The result proves that guide stars in the near infrared band are far more than those in the visible band in case of the same limiting magnitude. Star camera of infrared star sensors can adopt systems having smaller aperture or narrower field of view.
