Abstract

Systems and methods are provided for automated geolocation of a signal emitting device. A computing device is communicatively connected to a server coupled with a database. The computing device selects at least one signal from the signal emitting device for geolocation on a spectrum display and selects at least three apparatus units within a location or region. The at least three apparatus units are operable to detect and measure the at least one signal, thereby forming signal data; and the at least three apparatus units are not required to be synchronized. The database receives and stores the signal data from the at least three apparatus units. The server calculates distances from each of the at least three apparatus units to the signal emitting device based on a propagation model and derive a location of the signal emitting device based on the calculated distances.
