doi:10.7527/S1000-6893.2019.23560

Abstract

Abstract: Digital zenith camera as a star sensor is mainly used for high precision positioning on the ground. To improve the correctness and rapidity of star identification, the image coordinates of star points are first analyzed, and the coordinate transformation model is established. Then the bright stars in the field of view are selected to construct the navigation catalogue. Three bright stars are identified by the triangular star identification algorithm. The coordinate transformation parameters are calculated using the three bright stars, whose correctness is checked in the meantime. Transformation of the star image coordinates is performed based on the coordinate transformation model, followed by the matching of the transformed coordinates with the star image coordinates to identify the stars. The experimental data shows that this method can effectively reduce the identification time.

Key words: star sensor, coordinate transformation, bright stars, star identification, astrometry
