摘要：The present invention is a method and apparatus for automatic calibration ofwireless positioning system base stations. An automated system and method for
calibrating a location system comprises obtaining at least one position assertion with acorresponding base station-centric position assertion on at least on mobile
communication device. A latency calibration record is maintained which includes a currentbase station latency estimate for a base station controller. The measured positionassertion is analyzed in relation to base station-centric position assertion and the latencycalibration record, to develop a new base station latency estimate. The latencycalibration record is refined using the new base station latency estimate and the stepsare repeated to further refine the latency calibration record.
