Weighted-beacon Least Square Positioning Method Based on Measurement

In this paper, we propose a simple location positioning method based on our own IR-UWB system. First, we examine the sampling characteristics of pulse-arrival-time. Second, we propose a simple location positioning method (WB-LS) based on our observation. The WB-LS method takes the sampling characteristic at each beacon into consideration when it calculates the position of the tag. It shows a much improved location estimation performance (up to 50%) compared to the LS method which does not consider the difference of beacons.
