Abstract
A subject location tracking process is provided that includes the attachment of a system to a subject where the system includes a radiofrequency sensor integration module, an inertial tracking module, and a microprocessor. Radiofrequency signals are communicated from the radiofrequency sensor integration module to a remote radiofrequency transceiver beacon. A measured range is determined between the radiofrequency sensory integration module and the beacon. An error value E is then computed between the measured range and a predicted range. The predicted range is computed from the inertial tracking module alone based on positional data as to location and orientation of the system. The location data of the subject is determined with a microprocessor and displayed at the location. The present invention operates to provide a high degree of accuracy as to the position of a subject in spite of intermediate obstructions and without reliance on global position satellite systems, fixed reference signals, or line of sight.
