摘要/Abstract

摘要： 手机GNSS芯片可支持多模GNSS观测信号,其提供的原始观测量为高精度导航定位提供了可能,智能手机高精度导航定位成为研究热点之一。本文首先基于自研的反向RTK算法,设计并开发了一套基于智能手机的实时高精度定位系统,降低手机的计算压力;然后基于智能手机小米8,进行了大范围(覆盖深圳、武汉、北京)、多场景(城市开阔/遮挡,高速开阔/遮挡)的动态车载应用测试,用于验证系统的可靠性和可用性。测试结果表明:系统在各场景下均能稳定有效运行,在开阔环境下,小米8可实现亚米级的实时动态定位精度,精度最优可达0.21m。

关键词: 智能手机, 多模GNSS, 反向RTK, 实时高精度定位系统, 车载应用测试

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.

Key words: smartphone, multi-system GNSS, reverse RTK, real-time high-precision positioning system, vehicle-mounted application test
