RSSI-BASED INDOOR POSITIONING USING IBEACON AND INERTIAL NAVIGATION
Keywords:
Indoor navigation, RSSI, IBEACON, inertial navigation, smoothing and filtering of navigation data.Abstract
This article presents an indoor navigation system and the purpose of this study is to create and test a high-precision indoor positioning system using Bluetooth beacons and inertial navigation system sensors. The system determines the location of a mobile object by combining information from an inertial navigation system sensor with RSSI (Received Signal Strength Indication) indicators. The navigation system uses two types of information: Inertial navigation system data is more accurate in the short term, but the error increases over time, and RSSI position estimates have limited positioning error. It is anticipated that positioning accuracy can be significantly improved by using filtering and data smoothing methods by combining RSSI data from Bluetooth beacons with data from INS sensors.
