POSITION COORDINATE DETERMINATION APPARATUS AND METHOD IN INDOOR LOCATION MEASUREMENT SYSTEM
摘要
A position coordinates determining apparatus and a method for indoor location measuring systems are provided to precisely estimate the coordinates of a moving tag node in real time through a simple operation. A position coordinates determining method for indoor location measuring systems comprises the following steps of: selecting three fixed nodes among several fixed nodes; selecting two different fixed nodes among the selected fixed nodes in turns to obtain an intersection; selecting two different intersections among the obtained intersections in turns to obtain an intersection point; repeating all the steps until desired intersection points are all obtained; and calculating the average value of the obtained intersection points and estimating the location of a moving node.
