Leveraging Digital Maps to Visualize Data in Doppler Effect-based Localization System Relying on GNSS

This paper presents a localization solution exploiting the Doppler effect, digital maps and the Global Positioning System (GPS). To deploy such a system, the following steps must be completed: selecting a suitable GPS receiver, developing operating software, creating an app for displaying digital maps offline, choosing a software-defined RF receiver with a stable frequency reference, integrating the GPS receiver with the map and a radio within a software environment, and setting up a transmitter-receiver link. The second part of the research involves comprehensive tests of the integrated localization system and analyzing the empirical results obtained. The novel approach described in this article consists in the use of digital maps and GNSS data for dynamic visualization of transmitter location using the SDF method. The research was carried out in an NLOS environment.
