Abstract

Radio frequency (RF) geolocation is the process of using receivers to estimate the general location of a transmitter. One method of RF geolocation is to measure the received signal strength (RSS) at different locations around the transmitter. RSS-based geolocation systems are less expensive and less complex than other systems. Unmanned Aerial Vehicles (UAVs) can be used as a mobile platform for RSS-based geolocation systems. This paper will explore RSS measurements as a method for low-cost geolocation on a UAV. The geolocation system combines with a mapping system on the UAV to produce a 3D map with the estimated location of a RF emitter. Experimental results show a location accuracy of about 12.5 m.
