| Abstract: | With the development of smartphones with multi-system GNSS observations, the raw GNSS observations of the smartphones are feasible for high-precision positioning, which has become one of the research hotspots. In this paper, we develop a set of real-time high-precision positioning system for smartphones based on reverse RTK, which could reduce the computing pressure of smartphones. Based on Mi 8 smartphone, we perform a large-scale (Shenzhen, Wuhan and Beijing), multi-scenarios (urban open/blocking, highway open/blocking) dynamic vehicle-mounted application test to verify the reliability and usability of the system. The results show that the system can operate stably and effectively in all scenarios. Besides, we can achieve sub-meter real-time dynamic positioning accuracy under the open sky environment, with an optimal accuracy of 0.21 m. |
