Abstract

Currently provision of reliable PNT information in GNSS-challenged conditions is remaining a difficult task because of several factors which have a significant impact on signal propagation and its steady and proper reception such as multipath, attenuation or blockage of the GNSS LOS signal, interference by wide class of signals in GNSS frequency band. To improve the reliability of PNT information in outdoor urban environments, it is proposed to use UWB LNS due to low multipath effect on its signals. For this reason, the main purpose of this work is evaluation of the features of constructing LNS based on UWB signals in urban conditions, as well as comparison of error of navigation solution and plane coordinates based on GNSS and UWB signals. Two experiments described in this paper were conducted. The first experiment was aimed at determining the maximum operating range of UWB LNS, the second experiment was focused on evaluation of UWB LNS performance in outdoor urban environments. In conclusion discussion of obtained results is presented.

城市室外环境下UWB局部导航系统行人和车辆定位性能实验评价

目前，在GNSS面临挑战的条件下提供可靠的PNT信息仍然是一项艰巨的任务，因为有几个因素对信号的传播及其稳定和适当的接收有重大影响，如GNSS LOS信号的多径、衰减或阻塞、GNSS频段内宽类别信号的干扰。为了提高PNT信息在室外城市环境下的可靠性，由于其信号的多径效应较低，因此提出使用UWB LNS。因此，本工作的主要目的是评估城市条件下基于UWB信号构建LNS的特点，以及基于GNSS和UWB信号的导航解与平面坐标误差的比较。本文进行了两个实验。第一个实验旨在确定超宽带LNS的最大工作范围，第二个实验侧重于评估超宽带LNS在室外城市环境中的性能。最后对所得结果进行了讨论。
