Abstract
A system and method for determining the geolocation of a transmitter within or without a set of receiving stations. The system includes plural receiving stations which determine the time of arrival and the angle of arrival of a signal from a target unit. The signal determinations are communicated to a central processing unit which determines the geolocation of a radiating unit which would provide such times of arrival and angles of arrival. By use of both time of arrival and angle of arrival information at the central processing unit, the need for receiving stations to cover a desired geographic area is reduced.
