Precision Localization System Using UWF Radio Technology: Spring 2024

Precision Localization System Using UWF Radio Technology: Spring 2024 Team Members Kevin Tan, John Cobb, Dillon Holder, and Alexander Phan Faculty Advisor Dr. Tarek Youssef Elsayed Abstract The tracking of objects has been predominantly performed by GPS systems. But GPS systems have a limitation- they aren’t very accurate, and they don’t function correctly indoors. Ultra Wideband radio waves don’t have these issues and perform more accurately and reliably than Bluetooth connections. Our localization system uses at least one “tag” that initiates a signal to at least three “anchors” to range distance data between them. This data is used to calculate the location of the tag. A single room and the immediate adjacent hallway outside are mapped and measured using centimeters, and more rooms can be added modularly if desired. The tag can be put on any object desired to be tracked, and this is displayed and calculated within the user interface, which is visually shown. The three anchors actively used for calculation appear green, while the idle one is red. The anchors outside of the active room are grey. This system can support up to 32 tags per room.
