To maintain space situational awareness, development of space-based visible system has gained much attention in recent years. Because the angular measurement accuracy of space-based sensor is very sensitive to orbit determination, it’s necessary to analyze the factors of angular measurement error, which can provide references for optimal design of space-based sensor. In this paper, a space image synthesis system is developed to provide the image source for resident space object detection and extraction. Then image extraction error and pose error of observation platform are analyzed, with which that the angle measurement error decreases as the focal length and size of pixel increase under same image extraction error can be concluded. Compared with position and velocity error of satellite, attitude angle error has greater impact on angle measurement error of RSOs. By using Otsu method and mathematical morphology method, the angle measurement error of RSOs can be controlled within 7 arcseconds.
