Based on the theory of spectral filtering and the classical 7-layer model of atmospheric turbulence, the performance of the adaptive optics system on ground layer under different number of guide starsand different guide star arrangements is explored by using the theoretical filter model of the Ground Layer Adaptive Optics (GLAO) system and the error transfer function (ETF) under the condition of finite guide stars. The results show that when 1 guide star is in the center and the other 5 guide stars are evenly distributed around the edge of the field of view, the calibration performance of the system is the best. The research results have important guiding role and reference value for the multi-conjugate adaptive optics (MCAO) system (including GLAO system) of the one-meter new vacuum solar telescope being developed.
