Abstract :
This paper investigates a method of tracking remote transmitters using a fingerprint localization database generated by ray tracing. OpenStreetMap building data is used to model the area of interest, and a database of received signal strength (RSS), time-difference of arrival (TDOA), and angle of arrival (AOA) fingerprints is generated virtually along a grid. These fingerprints are then used to estimate the origin of incoming signals. Simulation of this method using three receivers and a 10m square grid demonstrates a localization accuracy within 15m.
