Abstract
In this article it is examined the influence between the projection size of the point light source and the detection error of coordinate center when projecting on the photo-sensitive matrix. With the help of simulation it is formed the dependence of detection error of coordinate from magnitude of dispersion radius projection in case of different position of light source relative to the receiver. Analized operating characteristic of two delimitation of coordinate algorithms: using maximal likehood method and using the centroid method. It is find of the ratio between the dispersion radius and size of receiver in the case of minimal error.
Keywords.: Point light source; detection error of coordinate; astronavigation; star tracker; centroid; maximal likehood method
