About this technology
Overview
A real-time locating system (RTLS) developed at the Johnson Space Center uses ultra-wideband (UWB) radio frequency (RF) signals for tracking and reporting the position of transmitter-equipped people and objects. The technology has 100 to 1,000 times finer granularity than conventional narrowband RF RTLS systems and achieves a tracking resolution of less than 1 percent of the range (tested up to 3,500 feet). The technology has a number of commercial applications including long-range tracking of emergency, military, and mining personnel in limited access or hostile environments where global positioning systems are not reliable. This method combines the advantages of accurate Time Difference of Arrival (TDOA) information achieved using UWB technology with the geometric advantages of two-cluster tracking to provide accurate location information at long ranges. This NASA Technology is available for your company to license and develop into a commercial product. NASA does not manufacture products for commercial sale.
