The accuracy of location methods based on received-signal-strength (RSS) measurements is highly variable, but the underlying causes are not well known. In this paper, narrowband measurements at five VHF frequencies are used to evaluate the accuracy of RSS-based location algorithms. The least squares algorithm is the most accurate if the propagation model is unbiased. Location error increases linearly with mean distance from transmitters and with RSS variation caused by shadow fading or varying… CONTINUE READING
