Angle Of Arrival (AOA) is a geolocation technique which triangulates location using two or more Lines Of Bearing (LOB) generated from direction finding techniques. Where many LOB are available, quality thresholding allows these to be used selectively, removing poor quality multipath affected signals to maximise geolocation accuracy.

Two or more LOB can be generated using a fixed network of two or more antenna arrays. Alternatively, a single mobile antenna array (using a Direction Finding Vehicle) can pinpoint location with our Cumulative Tracking feature.
