Analysis of BDS-3/GPS Data Quality and SPP Performance of Smartphone
Abstract We use the smartphone Xiaomi 11 Lite, which could track the B1I/B1C/B2a frequency of BDS-3 and the L1/L5 frequency of GPS, as the research object, and do static observation experiment and dynamic experiments with different sites respectively to analyze the quality of raw observation data of triple-frequency BDS and dual-frequency GPS output by smartphone and the performance of single-frequency SPP. The experimental results show that the low cost GNSS antenna of smartphone leads to poor signal quality, and the anti-interference of GPS L1 frequency and BDS B1C frequency of smartphone is strong. In static and dynamic experiments, the positioning result of BDS B1C frequency of smartphone is relatively stable. In static experiment, the positioning result of GPS L5 frequency is better than that of GPS L1 frequency, and in dynamic experiment, the positioning result of GPS L1 frequency is better than that of GPS L5 frequency.
