Outdoor positioning is based on Global Positioning System. However, it will cause high distance error rate when using them for indoor positioning. Therefore, the other researches propose another communication technology as indoor positioning method. In this paper we propose an indoor location system use Bluetooth Low Energy. Its advantages such as low cost and low power are appropriate to be used as beacon stations for indoor positioning Firstly, the proposed system measures distance between stations and object by Received Signal Strength Indication which is provided by Bluetooth Low Energy, and then a one-dimensional spatial filter is designed to obtain more accurate RSSI for improving the distance transformation. Subsequently, Use indoor positioning algorithms to calculate the object coordinates.
