Abstract:
Position and orientation tracking systems and methods include a transmitting antenna transmitting a radio frequency (RF) signal. At least one receiving antenna acquires the RF signal. One of the at least one receiving antenna and the transmitting antenna is designated a reference antenna. A processing unit determines a phase difference between the RF signal received by each receiving antenna and the reference antenna. The processing unit computes a position of the transmitting antenna with respect to the at least one receiving antenna in response to the phase difference determined for each receiving antenna.

Claim (Index 21):
A position tracking system comprising:\n a plurality of transmitting antennae each transmitting a radio frequency (RF) signal modulated by a first pseudo-random noise sequence, the plurality of transmitting antennae including at least three transmitting antennae and one of the plurality of transmitting antennae being designated a reference antenna; a receiving antenna configured to receive the RF signals transmitted by the plurality of transmitting antennae; a demodulator coupled to the receiving antenna and configured to demodulate the RF signals received by the receiving antenna using a second pseudo-random noise sequence; a processing unit determining phase differences between a reference recovered signal derived from the demodulated RF signal transmitted by the reference antenna and a recovered signal derived from the demodulated RF signal transmitted by each remaining transmitting antenna of the plurality of transmitting antennae, the processing unit computing a position of the receiving antenna with respect to the plurality of transmitting antennae based on the determined phase differences.
