Navigation is a prerequisite for the execution of service tasks by mobile robots. For that reason, an ultrasonic based trilateration system for mobile robot navigation is presented in the following. The Local Positioning System LoPS allows the determination of object positions in large areas. During development the main focus of attention has been put to cheap, robust and simple sensors. LoPS has been designed as a reference system for mobile robot localisation approaches, but the system is useful for all measuring applications requiring the determination of Cartesian coordinates.
