Webbstar detection, the image coordinates of the stars are converted to incoming star vectors and each star is identified autonomously using an internal star catalog [3]. This paper presents an improved star ID method based on an existing search technique. This method employs the intensity of imaged stars to increase the matching efficiency. WebbAbstract: Space target detection under the background of stars is one of the key techniques in space based optical measurement. In this paper, we proposed a space target detection algorithm based on star identification. First, the centroid of stars and space target is extracted by FPGA.

Webb18 maj 2024 · This paper deals with the identification of existing stars in the field of view of the star sensor. This step is known as star identification. This paper proposes three star-identification algorithms. In these algorithms existence of at least six stars in the sensor field of view is needed. WebbThe designed star sensor is based on CCD image sensor which has a flight heritage by the university's first satellite RISING. This system utilizes a pyramid algorithm for secure constellation identification and works with a maximum update frequency of 2 Hz. Its availability is also very high in terms of the satellite's operating angular velocity.
