Wireless positioning server using clock offset compensation and wireless positioning method using the same

PURPOSE: A wireless location measurement server using clock offset correction and a wireless location measurement method using the same are provided to minimize errors of a location estimate result by clock offset by measuring a relative clock frequency rate between beacons and compensating each beacon clock frequency. CONSTITUTION: Compensation pulse information including a clock count number of a first compensation pulse and a second compensation pulse is received from multiple beacons (200) which receive the first compensation pulse and the second compensation pulse from a step node. A relative clock frequency rate for clock offset compensation between the multiple beacons is calculated according to the beacon using a compensation pulse. The multiple beacons receive a location pulse from a tag of a location measurement target and receive location pulse information including the clock count number of the location pulse. A reception time point of the second compensation pulse in which the multiple beacons receive is synchronized with a same time point. Clock count information is calculated according to the beacon using the relative clock frequency rate corresponding to the synchronized time point.
