摘要	A guide star catalogue characterised by fewer guide stars, uniform distribution and high completeness is conducive to the improvement of star pattern identification and star tracking efficiency, and it has become an important study objective. A screening method, which takes "quasi-uniform distribution" of space solid angles as the principle and the size of the space solid angle corresponding to 4 degrees x4 degrees on the equator as the reference and divided the whole celestial sphere into 2,664 sub-blocks in sequence, is proposed in this paper. Based on this method, a "quasi-uniform" guide star catalogue with 2,937 guide stars was obtained. According to our ergodic statistical analysis of the whole celestial sphere, in a 12 degrees x12 degrees field of view, after the space solid angle method was used to divide the celestial sphere, the probability of emergence of three guide stars was 99.9% or above, while the number of guide stars decreased by 12.6% compared to the inscribed cube method. It can be concluded that when the completeness is equal, the space solid angle method is superior to the inscribed cube method in both capacity and distribution uniformity.
