Abstract :
Realtime Localization System is one of the several technologies in order to track the objects and target location. In this paper, a novel positioning system is represented, which is based on Ultra-Wideband technology. The proposed system is used to utilized the TDOA algorithm. In this method, the distance between the source and the target node is estimated by measuring the time of sending and receiving the message. Furthermore, we use a Zigbee protocol to implement a communication link between different nodes in this system. The software libraries are implemented independently. The result shows that our positioning system provides an accuracy of 20cm in terms of ranging. In addition, the data rate of the Zigbee link is 72byte per second. This amount of error can be greatly reduced by interpolating and calibrating custom environments. This accuracy is an acceptable and negligible error due to the error of 10 to 100 meters in expensive modules with GPS technology.
