Abstract
Localization system are widespread both outdoor and indoor and their objectives are various and of obvious importance: navigation, object and person localization and more. Indoor environments are particularly complex for position detection and localization; among several systems and the technologies used, the most commonly used is the Ultra Wide Band for its performance in terms of range and resolution. Any localization method strongly depends on a distance measurement and on its accuracy. In this paper after a short introduction on the state of art of indoor localization and on Ultra Wide Band technology, localization estimation technique is detailed in order to support the following sensor measurement characterization. The paper also report several measurements made on an indoor localization system based on UWB technology and extracts a noise model for the distance measurement. An exponential model for noise is extracted from measurements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
