Аннотация:—The paper presents a method for identifying the frame of a star sensor (SS), based on determinationof the star local features allowing its unique recognition. The star identifiers are located in a multidimensionalinteger feature space, and the relevant feature catalog presents a disperse array, which provides search-freestar determination. Examples of onboard implementation of feature catalog are presented, containing thestars up to magnitude of six. The required memory is estimated, and a method is proposed for compressingthe feature catalog to be recorded in the onboard computer memory. The frame identification algorithm usingthe reduced feature catalog is described in detail. The algorithm was tested on real sky frames.
