Approach for GNSS Constellation Based on Artificial Bee Colony Algorithm

Simultaneous satellite selection is a major challenge of multi-constellation satellite navigation systems today, since real-time positioning using all the visible satellites results in extremely high computation load. Therefore, quick and efficient satellite selection methods are highly demanded in the field of navigation. In this paper, for the first time, artificial bee colony (ABC) algorithm is adopted to select visible satellites for positioning in multi-constellation satellite navigation system with minimum geometric dilution of precision (GDOP) value achieved. The proposed approach is evaluated by simulation and the results show that the ABC approach has better performance in convergence and speed compared to that of the conventional particle swarm optimization (PSO) approach.
