WebbPyramid Star Identification The k - vector search method of Pyramid Star Identification technique has larger search scopes than the method used in the present study. The pyramid algorithm attempts to find a unique triangle as the identification base to narrow the search scopes. Webb1 nov. 2024 · Today, because of high accuracy of star tracker, this sensor is used more than others and other sensors are used as support devices [5,6,7].The task of star sensor is providing high-quality star images and matching them with catalogs of stars which are stored in sensor’s memory and identifying stars in image and finally determining attitude …

WebbA new highly robust algorithm, called Pyramid, is presented to identify the stars observed by star trackers in the general lost-in-space case, where no a priori estimate of pointing is available. At the heart of the method is the k-vector approach for accessing the star catalog, which provides a searchless means to obtain all cataloged stars from the whole …
Webb11 mars 2014 · The star matching or the star identification algorithm is the essential part of a star tracking algorithm. Several methods have been proposed for the task of star identification. However, they can be roughly divided into two categories; including graph based and pattern recognition algorithms. WebbThe Pyramid algorithm recognizes observed stars using the invariance of the angles between observed and cataloged stars. The k -vector range searching technique [ 2, 3] is the internal engine of Pyramid that facilitates a quick and robust Star-ID. The Pyramid algorithm is summarized in Appendix B.
Webb26 aug. 2024 · An artificial intelligence enhanced star identification algorithm is proposed for star trackers in lost-in-space mode. A convolutional neural network model based on Vgg16 is used in the artificial intelligence algorithm to classify star images. The training dataset is constructed to achieve the networks’ optimal performance.
