Abstract

A method for guiding a moving object to a target. The method comprising: transmitting a signal from one or more illuminating sources defined in a reference coordinate system; receiving the signal at three or more cavity waveguides disposed on the moving object; using one or more forward observers to determine the position of the target; fixing the one or more illuminating sources to the one or more forward observers; determining a position and/or orientation of the object in the reference coordinate system based on a strength of the signal received in the three or more cavity waveguides; and guiding the moving object to the target based on the determined position and/or orientation.

Claims

1. A method for guiding a moving object to a target, the method comprising:

transmitting a signal from one or more illuminating sources defined in a reference coordinate system;

receiving the signal at three or more cavity waveguides disposed on the moving object;

using one or more forward observers to determine the position of the target;

fixing the one or more illuminating sources to the one or more forward observers;

determining a position and/or orientation of the object in the reference coordinate system based on a strength of the signal received in the three or more cavity waveguides; and

guiding the moving object to the target based on the determined position and/or orientation.

2. The method of claim 1, wherein the one or more illuminating sources comprises two or more illuminating sources and the one or more forward observers comprises two or more forward observers, wherein at least two of the two or more illuminating sources are fixed to at least two of the two or more forward observers.

3. The method of claim 1, wherein the one or more illuminating sources comprises three or more illuminating sources and the one or more forward observers comprises three or more forward observers, wherein at least three of the three or more illuminating sources are fixed to at least three of the three or more forward observers.

4. The method of claim 1 further comprising providing position information from a GPS device to at least one or the one or more illuminating sources the one or more forward observers and the moving object, wherein the guiding is also determined based on the position information.

5. The method of claim 1 further comprising providing position and/or orientation information from an inertial devices on board the moving object, wherein the guiding is also determined based on the position and/or orientation information.
