An advanced precise position location and navigation system being developed for first responders and emergency rescuers is discussed in this paper. The paper will discuss details of the recent developments and the progress made in the design and development of a prototype wireless system which is very well suited for real-time positioning and tracking of first responders and emergency rescuers with a target of one meter accuracy in an indoor environment. The distance estimation is based on a time difference of arrival (TDOA) recovery approach and the Multicarrier-Ultrawideband (MC-UWB) signal structure being used is much easier to adapt to existing spectral assignments. The system level integration of the developed prototype receiver, transmitter and position location algorithms is described. The paper will present distance estimation results outdoors, and indoors, in the presence of multipath. Future design issues and improvements to the system to improve the position estimates will be reviewed.
Per- and polyfluoroalkyl substances (PFAS) are a group of chemicals used for their impressive stability, a property which has also led them to be found polluting virtually every sector of the environment-including our...
