Impact of Multipath GPS Sig nal Spreading on Precisi on of Us er Localization

This paper focuses on measuring the inaccuracy of localization using a global positioning system. It describes the types and causes of navigation errors as well as the impact of multipath signal spreading on determining the GPS location. The aim of the experiment is to quantify the degree of influence of GPS multipath signal spreading in urban environments compared with measurements in the open air. During the experiment, we have used a Holux M-1000C GPS device in the DGPS / SBAS mode using the EGNOS technology.
