Abstract
Disclosed herein is a wireless location determination system and method. A wireless location determination system of the present invention includes one or more location determination nodes (reception units) for calculating standard deviations of time intervals between pulses sequentially received from a location determination target, and estimating reliability values from the standard deviations. A location determination server receives messages, including the reliability values, from the location determination nodes, and obtains a location of the location determination target (transmission unit). Accordingly, the present invention can not only improve the resolution of location determination by correcting the distances between the location determination target and the respective location determination nodes, but also can easily observe the location determination performance of a relevant node by monitoring reliability values of the location determination nodes, and can regard the reliability values as measures for the observation of performance and the maintenance of location determination nodes.
