20 May 2005 A tracking technology for security personnel and first responders
Author Affiliations +
Northwest Nuclear, LLC (NWN), the Applied Physics Institute (API) at Western Kentucky University, and Crisis Prep Services, LLC (CPS) have developed a tracking technology for first responders and security personnel based upon the AeroScout system (a product of AeroScout, Inc.) and technologies developed independently by NWN, API, and CPS. These systems provide location information using 802.11XXX architecture by measuring the time of arrival of packets from a set of active radio frequency (RF) tags to a set of location receivers. The system can track and graphically display the location on maps, drawings, floor plans or photographs of tagged items on any 802.11-compliant devices (PDAs, laptops, computers, WiFi telephones) situated both outside and inside structures. This location information would be vital for tracking the location of first responders, security, and other emergency personnel during rescue operations; particularly, under adverse conditions (e.g., fires). NWN, API, and CPS have been improving the precision of the location measurement to an uncertainty of 20 cm or 8 inches (under certain conditions) and also developing algorithms to increase the accuracy. NWN and API personnel have developed: 1) special tags which indicate tampering or sudden movement and transmit briefly under these conditions, and 2) permanent and portable systems which can be deployed rapidly. Additional software created by Crisis Prep Services, LLC allows response force personnel to be tracked and located inside a building in real time as well as use the software and tags as a training and rehersal system. The location of each person is depicted on a drawing of the building and is displayed on a laptop computer or any other browser capable device.
