摘要/Abstract

摘要：

【目的】北斗卫星导航系统（Beidou Navigation Satellite System, BDS）由我国完全自主设计建造,是一项重要的国家空间基础设施,旨在为全球用户提供导航、定位与授时服务。当前,大众低成本智能设备卫星定位主要以美国全球定位系统（Global Positioning Systems, GPS）为主,北斗的出现能有效地减少对GPS的依赖。开展BDS在大众低成本智能设备,特别是智能手机上的应用研究,对发展北斗产业,服务经济社会和民生改善有着重要意义。【方法】本文选用了华为公司新发布的华为Mate40、Mate30、P40和P30智能手机,与同时采集的GPS数据进行了对比,采用伪距相位无几何组合法,分析了北斗在中国区域的智能手机终端原始观测值的数据质量,并采用标准单点定位和实时伪距差分定位方法,分析了静态、低速动态、中高速动态和高速动态场景下的定位表现。【结果】结果显示：中国区域内智能手机跟踪的BDS卫星数、观测噪声以及定位表现均优于GPS。【结论】表明我国自主研制的BDS系统能为大众用户低成本设备提供更优质的定位服务。

Abstract:

[Objective] The Beidou navigation satellite system (BDS) is an essential national space infrastructure designed and built entirely by China. It aims to provide navigation, positioning, and timing services for users worldwide. At present, the mass low-cost intelligent equipment satellite positioning is mainly based on the US's Global Positioning Systems (GPS). The emergence of BDS can effectively reduce the dependence on GPS. Research on the application of BDS in low-cost smart devices, especially smartphones, is of great significance for the BDS industry development, economic and social services, and improvement of people's livelihood. [Methods] In this study, the quality of the raw BDS observations of the smartphones from Huawei Mate40, Mate30, P40, and P30 in the region of China was analyzed by comparing with the GPS data collected simultaneously by code minus carrier method and the positioning performance under static, low speed, medium speed, and high-speed dynamic scenarios is evaluated using single point positioning and real-time kinematic pseudo-range difference method. [Results] The results show that the number of viewed satellites, observation noise, and positioning performance of BDS satellites tracked by smartphones in China is better than that of GPS. [Conclusions] Finally, it can demonstrate that the BDS system developed by China could provide better positioning services for low-cost equipment for mass users.
