Abstract

Nowadays, indoor positioning services of mobile phone with Bluetooth low energy (BLE) beacons are increasingly used. However, due to the indoor environment has dense multipath fading, the positioning system has low accuracy. In this paper, the accuracy study of trilateration method for indoor positioning with BLE beacons is presented. The indoor environment room with 9.0 m width, 10.2 m length and 3 BLE beacons is studied. The received signal strength (RSS) of each BLE beacon is measured by using mobile phone. The distance between each BLE beacon and mobile phone is evaluated using channel model. After that, the trilateration method is used to approximate the position of mobile phone. The accuracies, which are obtained from one, average five and average ten measurements, are studied. The distance errors of all positions and the cumulative distribution function (CDF) of the distance error are calculated and shown. The results show that the average multiple measurements tend to decrease the distance error.

BLE信标室内定位三边法精度研究

目前，使用蓝牙低功耗(BLE)信标的手机室内定位服务越来越多。然而，由于室内环境存在密集的多径衰落，使得定位系统的精度较低。本文研究了利用BLE信标进行室内定位的三边法的精度问题。对宽9.0 m、长10.2 m、3个BLE信标的室内环境室进行了研究。利用手机测量每个BLE信标的接收信号强度(RSS)。利用信道模型计算每个BLE信标与手机之间的距离。然后，使用三边法来近似手机的位置。研究了一次测量、平均五次测量和平均十次测量的精度。计算并显示了各位置的距离误差和距离误差的累积分布函数(CDF)。结果表明，平均多次测量有减小距离误差的趋势。
