Abstract This paper studies the random model of Huawei P30 smartphone positioning with GPS/BDS/GLONASS/Galileo and other multi-system. It focuses on the evaluation of pseudorange noise when using multi-system mobile phone observations and analyzes the influence of different random models on the pseudorange single point positioning accuracy of mobile phone. The results show that the satellite pseudorange noise of different systems of Huawei P30 smartphone varies greatly. The mean square error of pseudorange noise of GPS, BDS, GLONASS and Galileo are 5.30 m, 2.75 m, 7.92 m and 1.07 m, respectively. When using the random model of signal-to-noise ratio+inter system weighting, the positioning performance of mobile terminal is the best. Compared with the traditional altitude angle model, the pseudorange single point positioning accuracy in E, N and U directions is improved by 36.12%, 25.79% and 31.30%.
