20130241774 | WIRELESS POSITIONING SERVER USING CLOCK OFFSET CALIBRATION AND WIRELESS POSITIONING METHOD USING THE SAME - A wireless positioning server using clock offset compensation and a wireless positioning method using the same. The wireless positioning server using clock offset compensation estimates a precise position of a tag requiring position information by effectively predicting information regarding a distance between a beacon for performing positioning and the tag requiring position information. An error in the positioning estimation result due to a clock offset is minimized by measuring a relative clock frequency ratio between beacons and by compensating for clock frequencies of the beacons when a distance between a beacon and a tag is estimated. | 09-19-2013 |
