Abstract

Today, modern autonomous vehicles cannot function fully without a positioning system. In many cases, some vehicles even require their own positioning system to ensure their accuracy and stability in movement. In this paper, the authors present the design of an indoor positioning system (IPS) using Ultra-Wide Band combined with Triangulation method. The system consists of 3 Anchor nodes used as waypoints and 1 Tag node attached to the object. Through the distance from the Tag node to different waypoints, IPS figures out the position of the object in real time. After the design, the system was tested by experimental methods combined with specialized software. The results indicate that the positioning system has located the object with an error of less than 10 cm. This error is much smaller than that of the Global Positioning System (GPS). With the design parameters achieved, the positioning system is suitable for application in the navigation system for Robots and autonomous vehicles.
