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 17):
A method of tracking a position of a transmitting antenna, comprising:\n receiving a radio frequency (RF) signal modulated by a first pseudo-random noise sequence, transmitted by the transmitting antenna, with at least three receiving antennae; designating one of the at least three receiving antennae as a reference antenna; demodulating the RF signal received by the reference antenna with a second pseudo-random noise sequence to produce a reference recovered signal; demodulating the RF signal received by each remaining receiving antenna of the at least three receiving antennae with the second pseudo-random noise sequence to produce recovered RF signals; determining phase differences between the reference recovered signal and the recovered signals; and computing the position of the transmitting antenna with respect to the receiving antennae based on the computed phase differences.
