A technique for determining relative yaw using phase windup

Abstract From the Canadian patent

A technique uses "phase windup" to determine relative yaw of a craft from a plurality circularly polarized signals transmitted from one or more transmission sources. , A first difference in carrier phase measurements taken simultaneously at time t1 is , determined for first and second circularly polarized signals from a given transmitting , source A second difference is then determined from simultaneous carrier phase measurements taken at time t2. A third difference which is the difference , between the first and second differences, is then used to determine the relative yaw based on a , difference in wavelengths of the two signals. If more than one transmitting source is in , view, …
