Abstract
A method for estimating a range between a radio signal emitter and a receiver. A first range estimate is obtained from a signal strength of a received signal and a path loss model with predetermined path loss parameters. This range estimate is further corrected with a systematic bias depending upon an actual finite sensitivity of the receiver. Optionally a corrected variance of the range estimate can be calculated.
