Ultrasonic local positioning system.

Abstract

The purpose of this project is to implement a system that can provide different types of position and location information in a coordinate system, which can be scalable in order to increase its coverage. An arrangement of ultrasonic nodes is proposed to provide a mobile system with position and location information. This arrangement is also expected to ease the direction tracking of a node of interest. The increasing importance of positioning systems is an important reason to develop the proposed system. Positioning systems can estimate data like physical space, position and object orientation; however, the lack of accuracy and proper scaling will make useless the estimated data. The usual GPS and RFID systems can not provide enough accuracy as a result of the distortion naturally introduced during the navigation within indoor spaces. This is the main motivation to develop a Local Positioning System.
