Design and Implementation of Area Positioning System Based on UWB

In scenarios requiring precise location information like smart campus, common positioning technologies such as ZigBee, Bluetooth and WIFI have low accuracy and cannot meet high-precision positioning needs, while differential GPS (DGPS) can achieve high-precision positioning, but its equipment is relatively expensive. To address these problems, this paper designs an area positioning system based on UWB technology, which uses the Chan-UKF algorithm for positioning on the basis of the excellent ranging performance of ultra-wideband technology (UWB). The performance of the designed system is verified through experiments. The system can effectively suppress interference caused by complex environments and achieve low-cost and low-power positioning in applications that require high-precision positioning, such as smart campuses, golf courses, indoor parking lots, etc.
