Accuracy Analysis of Broadcast Ionosphere Model of Global Navigation Satellite System
Abstract We analyze the differences between the Beidou ionosphere, GPS Klobuchar, and NeQuick Galileo models, and the accuracy of Beidou ionosphere models are compared with other global ionosphere models using the global ionosphere maps of IGS analysis center as the reference value. The results show that the BDGIM model possesses the best global ionosphere delay correction precision, especially in China and its surrounding areas, where the corrected percentage can reach 77.01%.
