Influence of UTC parameters generating method on BDS positioning accuracy

Based on analysis of existing UTC parameters generating method, a new method for generating UTC parameters is proposed. Only changing the way of generating UTC parameters, the timing precision is improved from the level of tens of nanoseconds to nanoseconds when using the proposed method. And the positioning accuracy is also improved. In the paper, influence of the proposed method on BDS positioning accuracy is analyzed in theory and then the experiment platform is built and the improvement of user positioning accuracy is verified by the short baseline and long baseline experiment. Results show that the positioning accuracy of Lintong and Sanya users is improved after using the traceability method proposed in this paper.
