摘要

全球导航卫星系统(GNSS)支持越来越多的智能交通系统(ITS)应用和基于位置的服务，包括防撞、电子收费、车队管理和无人机系统(UAS)导航。本文对GNSS进行了详细的性能分析，并以城市环境中的失效模式为重点进行了关键案例研究。考虑城市结构对GNSS性能的影响，提出了一种基于轨迹优化的制导增强策略。作为初步评估，对城市环境中具有代表性的UAS操作进行了模拟案例研究，以证实开发的模块。

GNSS Performance Modelling for Positioning and Navigation in Urban Environments

The Global Navigation Satellite System (GNSS) supports a growing number of several Intelligent Transport System (ITS) applications and location based services including collision avoidance, electronic toll collection, fleet management and Unmanned Aircraft System (UAS) navigation. This paper performs a detailed performance analysis of GNSS with a focus on failure modes in urban environments as a critical case study. A guidance-based augmentation strategy based on trajectory optimization is developedwhich accounts for the influence of urban structures on GNSS performance. A simulation case study representative of UAS operations in urban environments was performed as a preliminary assessment to corroborate the developed modules.
