N2 - In order to analyze the positioning accuracy of the four-quadrant detector, this paper deeply studies the positioning principle of the four-quadrant detector, establishes the mathematical model of azimuth standard deviation based on Gaussian facula, and deeply analyzes the influence of each factor on the positioning accuracy from the three influencing factors of facula position, facula radius and signal-to-noise ratio. The results show that the positioning accuracy can be effectively improved by improving the signal-to-noise ratio, using smaller light spot and making the light spot as close to the center of the detector as possible.
