Title: Satellite selection algorithm and positioning analysis for combined BD-2/GPS navigation system
Abstract: To resolve the conflict between positioning accuracy and rapid positioning when using combined satellite navigation system,a new algorithm for choosing visible stars is presented.The algorithm combines visible satellite elevation angle with genetic algorithm,and takes GDOP calculation model as the fitness function in genetic algorithm to judge the quality of solutions,so as to achieve the effect of rapid positioning.Through the comparison of GDOP and the running time acquired by this algorithm and the method of optimum geometric dilution of precision,it is found that the method of geometric dilution of precision achieved by this method is closer to the optimal value,and the computing time of the satellite selection algorithm is reduced.Data analysis shows the advantages of the algorithm in the aspect of real-time performance and feasibility.
