It measures correlations and calculates actual positional probabilities using "augmentednTime Difference of Arrival (TDOA) andlor Power on Arrival (POA) techniques. In addition, it gives a bearing (Angle of Arrival) based on received power at each antenna. Measurements from these different techniques can be overlaid onto a wide variety of
