Effects Of Distance, Antenna, And Channel On An Ultra Wide Band Location System, And Quantifying Them To Increase Accuracy, Nicholas Alexander Cavopol

Masters Theses

Localization has been evolving rapidly over the last 20 years, especially in the wireless world. From the advent of GPS, as well as the personal smart phone, localization has become accessible to most of the developed world. From the ability to find ones’ smartphone using a computer, to being able to locate ones’ keys using radio frequencies, there are many ways that localization has entered our lives in the last few years, however most of these either do not have high accuracy, or are only accurate in an outside environment. For indoor tracking, new technologies have been developed to help …

Multi-Tag Access For A High Precision Ultra-Wideband Localization System, Nathan Carl Rowe

Masters Theses

Ultra-Wideband (UWB) wireless positioning systems have many advantages for track- ing and locating items in indoor environments. Surgical navigation and industrial process control are potential applications for high accuracy UWB localization systems with millimeter or sub-millimeter accuracy. I present improvements made to an existing high accuracy, multi-tag, UWB localization system. The goal of this thesis was to improve the multi-tag performance of this system while maintaining the high localization accuracy, and to utilize the UWB system for digital communications allowing the existing narrowband 2.4 GHz transceiver to be eliminated.

This thesis presents a proof-of-concept for a multi-tag, UWB localization system …
