Abstract
An RF position tracking system for wirelessly tracking the three dimensional position of a device that transmits a radio signal. The device has an antenna and at least one inertial sensor. The system uses a plurality of receiver antennas to receive the device's radio signal at each antenna. The device also incorporates an inertial sensor to improve position stability by allowing the system to compare position data from radio signals to data provided by the inertial sensor.
