Abstract
A system and related method for navigation and orientation determination in an indoor or GPS-denied environment mounts a static reference transceiver (SRT) at a known, fixed position within the environment, the fixed position referenced by a coordinate reference frame (CRF) of the SRT. The SRT communicates its position to mobile dismounted units within the environment, determining a range and orientation angle of each mobile unit relative to the SRT CRF based on response signals received from the mobile units. The SRT provides the determined SRT-CRF-referenced ranges and orientation angles to the mobile units, which may share orientation data with each other or relay the SRT-referenced location data to other mobile units not within line of sight of the SRT.
