With the development of mass market, the demand for high-precision and high-stability navigation and positioning functions of Android smart phones is increasing. However, compared with the traditional receiver, the positioning accuracy of the mobile phone is seriously degraded caused by low gain and weak mulitpath suppression ability. Many scholars have analyzed the signal quality of mobile phones and improved the stochastic model algorithm, which are mainly based on certain types of mobile phones such as xiaomi 8 and huawei mate 20. In view of the fast iterative development of mobile phones, as well as different GNSS chips have different positioning performance, here we analyze Huawei’s new mobile phone P40 pro to test its position accuracy. We conduct two sets of static and dynamic experiments to verify the positioning performance for the mobile phone. The results show that it takes about 5 min for the static PPP (Precise Point Position) error to converge to 2 m, and 15 min to converge to 1 m. The RMS (Root Mean Square) of position bias in the E, N and U directions are 0.25, 0.10 and 0.57 m, respectively. Compared with the results of SPP (Single Point Position), the accuracy of PPP results is improved in three directions.
