description: The introduction of Bluetooth Low Energy (BLE)  technology provides new opportunities that the Global Positioning System (GPS) could not provide for indoor localization. In this article, we propose a real-time indoor tracking and positioning system using BLE beacon and smartphone sensors. Up to now, most of the system is using Pedestrian Dead Reckoning (PDR). The initial position is considered to have a high impact on the accuracy of PDR, so, based on the analysis of received signal strength (RSS), we present a method to estimate the approximate distance, then, estimate the initial position through Trilateration technique. Next,  we propose a lightweight and reliable fingerprintmethod. This  method addresses two problems: (1) to correct errors due to  the initial position error and orbital drift of PDR, (2) to reduce theamount of data, number of reference points and collecting  data time. The proposed system is implemented on  hesmartphone as an application.To verify the accuracy of the system, we performed some experiments. The results show that the system not only achieves high accuracy but also the high  performance with average complexity and low cost.
