Abstract

Global Navigation Satellite System (GNSS) constitutes the foremost provider for geo-localization in a growing number of consumer-grade applications and services supporting urban mobility. Therefore, low-cost and ultra-low-cost, embedded GNSS receivers have become ubiquitous in mobile devices such as smartphones and consumer electronics to a large extent. However, limited sky visibility and multipath scattering induced in urban areas hinder positioning and navigation capabilities, thus threatening the quality of position estimates. This work leverages the availability of raw GNSS measurements in ultra-low-cost smartphone chipsets and the ubiquitous connectivity provided by modern, low-latency network infrastructures to enable a Cooperative Positioning (CP) framework. A Proof Of Concept is presented that aims at demonstrating the feasibility of a GNSS-only CP among networked smartphones embedding ultra-low-cost GNSS receivers. The test campaign presented in this study assessed the feasibility of a client-server approach over 4G/LTE network connectivity. Results demonstrated an overall service availability above 80%, and an average accuracy improvement over the 40% w.r.t. to the GNSS standalone solution.

对“移动智能设备中的DGNSS协同定位：概念验证”的更正

全球导航卫星系统（GNSS）在越来越多的支持城市交通的消费级应用和服务中构成了最重要的地理定位提供商。因此，低成本和超低成本的嵌入式GNSS接收机在很大程度上已经在智能手机和消费电子等移动设备中无处不在。然而，有限的天空能见度和城市地区引起的多径散射阻碍了定位和导航能力，从而威胁到位置估计的质量。这项工作利用了超低成本智能手机芯片组中原始GNSS测量的可用性，以及现代低延迟网络基础设施提供的无处不在的连接，以实现协同定位（CP）框架。提出了一项概念验证，旨在证明在嵌入超低成本GNSS接收器的网络智能手机中仅GNSS CP的可行性。本研究中提出的测试活动评估了客户端-服务器方法在4G/LTE网络连接上的可行性。结果表明，GNSS独立解决方案的总体服务可用性超过80%，平均精度提高超过40%的w.r.t.。

期刊介绍： The scope of the Transactions is threefold (which was approved by the IEEE Periodicals Committee in 1967) and is published on the journal website as follows: Communications: The use of mobile radio on land, sea, and air, including cellular radio, two-way radio, and one-way radio, with applications to dispatch and control vehicles, mobile radiotelephone, radio paging, and status monitoring and reporting. Related areas include spectrum usage, component radio equipment such as cavities and antennas, compute control for radio systems, digital modulation and transmission techniques, mobile radio circuit design, radio propagation for vehicular communications, effects of ignition noise and radio frequency interference, and consideration of the vehicle as part of the radio operating environment. Transportation Systems: The use of electronic technology for the control of ground transportation systems including, but not limited to, traffic aid systems; traffic control systems; automatic vehicle identification, location, and monitoring systems; automated transport systems, with single and multiple vehicle control; and moving walkways or people-movers. Vehicular Electronics: The use of electronic or electrical components and systems for control, propulsion, or auxiliary functions, including but not limited to, electronic controls for engineer, drive train, convenience, safety, and other vehicle systems; sensors, actuators, and microprocessors for onboard use; electronic fuel control systems; vehicle electrical components and systems collision avoidance systems; electromagnetic compatibility in the vehicle environment; and electric vehicles and controls.
