Abstract
In this paper, we propose a method to improve the accuracy of positioning by adding angle and distance validation to the existing Bluetooth-based positioning method using the angle of arrival. In the existing positioning method, an error occurs in the positioning value due to a multipath phenomenon induced in a non-visible distance environment. The proposed method derives the maximum and minimum angles of arrival that can be measured in consideration of the moving speed of the positioned device, and then examines whether the measured angle of arrival exceeds the range of the maximum and minimum angles of arrival. The accuracy of positioning is improved by conducting a distance validation check to see if the location of the device to be positioned and the distance to the positioning device exceed the effective distance. A simulation was conducted to analyze the positioning performance between the proposed method and the existing method, and it was confirmed that the positioning performance was improved through angle and distance validation compared to the existing method in a situation where the positioning error increased through the simulation results.
