Article: Accurate positioning system in complex environment based on Beidou dual frequency differential positioning technology Journal: International Journal of Information and Communication Technology (IJICT) 2025 Vol.26 No.3 pp.1 - 24 Abstract: Due to the differences between the orbit composition and error processing methods of Beidou satellites and GPS, the original GPS technology needs to be optimised when applied to Beidou satellites. Then, this paper makes a systematic analysis of the basic principle of satellite positioning (SP) through pseudo-range single point positioning (SPP), and uses static reference stations with accurate known positions to dynamically locate mobile base stations and mobile stations. At the same time, for the mobile base station and mobile station, this paper respectively uses SPP method and dynamic positioning (DP) method to calculate the baseline length between the two stations, and carries out baseline calculation experiments for the mobile base station and mobile station in different motion scenes. The results show that the accuracy of baseline length calculated by using DP is better than that by using SPP. Therefore, the method proposed in this paper can be applied to vehicle and pedestrian navigation to improve the navigation effect.
