| Abstract: | WT5BZ]Guide star catalog is significant for identifying star map, acquiring final attitude. The capacity, store manner, store content and read manner of the guide star catalog are key factors which influence the time and efficiency of star map identification. The paper introduces the method which adopts spherical matrix method for storing and reading guide star catalog, and elaborates the selecting rules and storing content on guide stars. Using spherical matrix method, the rough region of guide stars can be searched rapidly in all celestial sphere, that storing midyear average position and the angular distance between guide star pairs can further reduce sight position transformation time and star map identifcation time.
