Locating and tracking resources (e.g., personnel, equipment, and materials) is critical in many industrial applications for monitoring productivity and safety. In construction, various technologies (e.g., global positioning systems (GPS), radio frequency identification (RFID) and radio frequency (RF) localization) have been proposed. However, the performance of these types of technologies is not well understood for this particular application. This paper presents methods for evaluating the static and dynamic performance of commercially-available UWB tracking systems in free space and under realistic construction environments. In addition, a static performance model for estimating position error as a function of receiver position and initial calibration error was also developed. Applications where such real-time localization and tracking technologies may be useful are also discussed.
