Star Sensor Simulation with Application of the k-NN Method in Star Identification Problem

Abstract

Abstract Simulation of the navigation systems is required to develop efficient, reliable, and accurate algorithms for orientation problems. In this paper the astronavigation system is considered, and the star sensor simulation based on algorithmic mathematical model is discussed. The algorithms include the starry sky image obtaining, data processing, and stars identification. Two modifications of the known stars identification algorithm are proposed and related to the use of k-NN method in identification and stars selection criteria for increasing computational efficiency. Simulation of the described approach for star sensor is performed in MathWorks MATLAB. The simulation results show adequate results.
