Development of a Mobile Indoor Navigation System Based on Bluetooth Beacons

The goal of the graduating work is to create Indoor Navigation System (INS) based on Bluetooth beacons. It is difficult to navigate in the buildings with complex structure for people who are not familiar with them. Additionally, on the streets where buildings are located alongside with each other the usage of Global Positioning System (GPS) is quite complicated due to weak, noisy signals or in case of only reflected signals existence. In such situations INS provides an opportunity to determine user’s location how it can be done outdoors based on satellites. Implementation of INS can be achieved in several ways, but the most accurate solution can be achieved using Bluetooth beacons. This approach has some fluctuations which can be minimized using optimized algorithms for data collection and filtering. As part of this work beacons from the company “Estimote” were chosen. For statistical noises disposal Kalman filter is used. For finding user’s location trilateration algorithm is used. It allows to define device’s relative position with beacons expanding less calculation. Result of this project is an Indoor-navigation system which contains software part as mobile application that implements data collection, signals filtering and user’s positioning on the map and hardware part as configured beacons.
