Analysis of Real-time Beidou Precise Point Positioing Accuracy of Mobile Phone Terminal

With the continuous development of China's Beidou navigation and positioning system (BDS), Beidou widearea real-time precise positioning system is an important part of Beidou system, meeting the needs of the high-precision location service in various industries of the national economy. Based on the real-time high-precision orbit, clock and ionospheric products provided by Beidou wide-area real-time precise positioning service system, this paper uses mobile phone terminals which support Beidou wide-area real-time precise services to verify and evaluate real-time products accuracy and single frequency precise point positioning (PPP) accuracy. The experimental results show that the horizontal positioning accuracy of the realtime BDS single-frequency PPP of mobile phone terminal is 1 to 3 meters and the vertical positioning accuracy is 1.5 to 3.5 meters under the condition of good observation environment.
