摘要

目前,GPS和GNSS系统是智能交通系统中最常用的定位方法。然而,广泛使用的GPS系统受到卫星可用性和多径信号带来的精度下降的影响。在城市峡谷中尤其如此,那里的建筑物经常阻挡和反射GPS信号。为了忽略或纠正多径信号,以前的研究考虑了建筑物的几何形状。然而,对于大多数车载定位系统来说,计算和检索整个城市区域的建筑物几何形状仍然是不切实际的。该系统利用了大多数公共汽车被限制在单一路线上的事实,使系统能够先验地存储沿着整个公交路线的建筑几何形状。位置修正是根据已知的卫星位置和沿途建筑物的多径信号计算得出的。提出了一种厘米级精确的GPS系统,而不需要更昂贵的设备。

RTKLIB-based GPS localization for multipath mitigation in ITS applications
Currently, GPS and GNSS systems are the most popular means of localization in Intelligent Transportation Systems. However, widely available GPS systems suffer from precision degradation brought about by satellite availability and multipath signals. This is especially true in urban canyons, where buildings often obstruct and reflect GPS signals. In order to ignore or rectify multipath signals, previous studies have taken into account building geometries. However, computing and retrieving building geometries for entire urban areas is still impractical for most on-board localization systems. The proposed system exploits the fact that most Public Utility Buses are constrained to a single route, enabling the system to store building geometries along the entire bus route a priori. Position corrections are computed from known satellite positions and multipath signal computations on buildings along the route. A centimeter-level accurate GPS system is presented without the need for more expensive equipment.
