Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
Indoor positioning is a technique that is used to locate a mobile device in indoor environment in real or near real-time. The demand for indoor positioning system as a location based system is becoming more and more widespread. However, the field has not gain much success as outdoor positioning system.
The objective of this thesis work is to design and implement an indoor positioning system that relies on ultra wide band technology. The report also describes the way how to implement IEEE802.15.4a physical layer and medium access layer .The system uses time difference of arrivals technique to estimate the position of the mobile device.
Through an evaluation of our system, we conclude that ranging can reach an accuracy of ±20cm in line of sight measurement and ± 50cm for non-line of sight measurement. But the localization that is achieved has an accuracy is up to ±1.1m, we believe this can be improved by having all device to be synchronized effectively.
