A Preliminary Study About Star Image Processing Method in Harsh Environment
Communications in Computer and Information Science, 2021The star sensor is a high precise attitude measurement equipment for the spacecraft, and star identification is one of the key techniques of star sensor’s attitude determination. Star tracking mode is the main working mode of the star sensor. However, during star tracking, when the star sensor is in the harsh environment, the star imaging is seriously ...

Improving night sky star image processing algorithm for star sensors
Journal of the Optical Society of America A: Optics and Image Science, and Vision, 2014In this paper, the night sky star image processing algorithm, consisting of image preprocessing, star pattern recognition, and centroiding steps, is improved. It is shown that the proposed noise reduction approach can preserve more necessary information than other frequently used approaches. It is also shown that the proposed thresholding method unlike

Long-integration star tracker image processing for combined attitude-attitude rate estimation
Proceedings of SPIE, 2013A method is proposed for extracting attitude data from streaked star images using traditional image processing methods. The process enables collection of both attitude and angular velocity estimates from streaking star images, where traditional star identification methods would produce poor results.

Star sensor could work independently ignoring the outside interference, but the disadvantages of star sensor are low output frequency and the limitation in cloudy or rainy day. SINS/CNS integrated navigation system exactly makes up for the deficiencies. However, the practical environment of the surface ship with SINS/CNS integrated navigation system is
