众所周知，全球导航卫星系统技术从一开始就在某些运行环境中存在局限性，包括在低功率卫星信号可能被阻断或分散的任何地方。这就产生了各种综合解决办法，旨在扩大和改进全球导航卫星系统在不利条件下的性能。近年来，这些解决方案中包括使用三维地图来支持几种新技术，包括“阴影匹配”，其试图将城市地区建筑物的破坏性影响转化为实际增强位置确定的方法。
From their beginning, GNSS technologies were known to have limitations in certain operating environments, including anywhere that the low-power satellite signals could be blocked or dispersed. This has given rise to a variety of integrated solutions designed to extend and improve the performance of GNSS under adverse conditions. Among these solutions in recent years is the use of three-dimensional maps to support several new techniques, including “shadow-matching,” which seek to turn the disruptive effects of buildings in urban areas into a method for actually enhancing position determination.
