Abstract

This study presents an Android-based cooperative positioning (CP) architecture to improve the GNSS positioning performance on mobile devices. SBAS (Satellite Based Augmentation System) augmentation increases positioning accuracies significantly by sharing corrections between SBAS-enabled and non-capable devices via wireless connection or using a central server. The Indian GAGAN (GPS Aided GEO Augmented Navigation) is employed and assessed in the experiments. If GAGAN corrections are applied, all three chosen mobile devices showed a positioning accuracy improvement of around 95 %. The average 2D RSME was reduced from 75.23 to 1.35 m for the single-frequency GNSS smartphone Xiaomi Redmi Note 8 and from 33.25 to 1.62 m for the dual-frequency Google Pixel 4. As expected, the third GIS mapping device, Stonex S70 tablet, showed the highest performance, achieving sub-meter positioning accuracies. Thus, the experiment has proven the suitability of GAGAN augmentation for mobile devices, providing positive insight for further development of the CP architecture.

在智能移动设备上实施 GAGAN 增强技术并开发合作定位架构

本研究提出了一种基于安卓系统的协同定位（CP）架构，以提高移动设备的全球导航卫星系统定位性能。SBAS（基于卫星的增强系统）增强通过无线连接或使用中央服务器在支持 SBAS 的设备和不支持 SBAS 的设备之间共享校正，从而显著提高定位精度。实验中采用并评估了印度的 GAGAN（GPS 辅助地球同步轨道增强导航）。如果应用 GAGAN 修正，所有三个选定的移动设备的定位精度都提高了约 95%。单频 GNSS 智能手机小米红米 Note 8 的平均二维 RSME 从 75.23 米降低到 1.35 米，双频 Google Pixel 4 的平均二维 RSME 从 33.25 米降低到 1.62 米。不出所料，第三台 GIS 制图设备 Stonex S70 平板电脑的性能最高，定位精度达到亚米级。因此，该实验证明了 GAGAN 增强技术适用于移动设备，为进一步开发 CP 架构提供了积极的启示。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
