Abstract We analyze the quality and noise characteristics of BDS triple-frequency observation of Huawei P40 mobile phone. Comparing with the measurement receiver, we find that the Hisilicon chip of P40 mobile phone has good capability of capturing BDS-3 signal. The signal-to-noise ratios of B1I, B1C and B2a signals are slightly lower than that of the measurement antenna, and there are system errors related to the terminal chip for the three signals. The external antenna zero-baseline results show that the zero-baseline positioning accuracy of Hisilicon chip of P40 mobile phone reaches mm level and the pseudorange and carrier phase noise have reached the level of measurement receiver noise accuracy. The pseudorange noise of B2a is smaller than 0.5 m, and the carrier phase noise of three signals are smaller than 2 mm.
