Abstract:

A position and orientation determining system and apparatuses including a first radio frequency (RF) device having a first constellation of antennae including at least two receiving antennae and at least one transmitting antenna, and a first radio unit in communication with the first constellation of antennae, a second RF device having a second constellation of antennae including at least three receiving antennae and at least one transmitting antenna, and a second radio unit in communication with the second constellation of antennae, and a processor operatively coupled to at least one of the first or second RF device and configured to determine a three-dimensional position and three-axis angular orientation of the first RF device relative to the second RF device based on a carrier phase difference (CPD) measurement of distance difference based on signals received between each discrete pair of receiving antennae in the first constellation of antennae and received signals between each discrete pair of receiving antennae in the second constellation of antennae.
