Abstract

The application of consumer grade hardware and complexity scenes are the key limits for high accuracy of GNSS positioning and navigation service in smartphones. In the study, the comparisons for the quality analysis of GNSS observations among Huawei Mate 20, Xiaomi MI 8 and Huawei P 20 smartphones was firstly carried out. Secondly, we developed the receiving software on the Android platform for connecting the network RTK service. The high quality GNSS observations can be achieved after removing the atmosphere errors with network RTK service. Then, the high accuracy positioning results can be carried out in smartphones. The study shows that the static positioning accuracy of Mate 20, MI 8 and P 20 can converge to the centimeter-accurate within 20 minutes and the ambiguity-fixed solution accuracy can reach the centimeter by using network RTK positioning method. The kinematic positioning accuracy was greatly affected by the observation environment. The horizontal positioning accuracy of the three smartphones is 0.31 m, 0.021 m and 1.80 m, respectively.
