Indoor Positioning System Based on Zigbee and Inertial System

Indoor positioning system based on Zigbee is to obtain the RSSI value to calculate the distance between point and point rely on empirical formula, then determine the location of the positioning point.But there is a big error in the positioning result in this location method because the signal intensity of Zigbee is very easy to be disturbed by the external environment, and it is difficult to compensate for the complex and changeable environment in the room. So, in this paper, we design a system based on the Zigbee indoor positioning system, and using the inertial system to stable po University sitioning result, to improve the positioning accuracy of Zigbee indoor positioning system.
