Claim 10:
11. A navigation system for one or more vehicles located within a control volume, comprising:
a first camera configured to observe the one or more vehicles and first, second and third reference points within a first field of view, wherein the first, second and third reference points have first, second and third known spatial positions, respectively, and wherein each of the first, second and third known spatial positions is known with respect to an origin located within the control volume, the first camera being further configured to produce a first output signal from observation of the observed vehicles and reference points, wherein the first output signal is representative of a first two-dimensional image of the control volume as viewed from the first camera;
a second camera configured to observe the one or more vehicles and the first, second and third reference points within a second field of view, the second camera being further configured to produce a second output signal from observation of the observed vehicles and reference points, wherein the second output signal is representative of a second two-dimensional image of the control volume as viewed from the second camera;
a processor operatively connected with the first and second cameras and configured to determine a respective spatial position for each of the one or more vehicles from the first and second output signals; and
a transmitter operatively connected with the processor and configured to transmit one or more messages into the control volume, wherein the one or more messages contain a respective set of three-dimensional spatial coordinates for each of the one or more vehicles;
wherein the one or more vehicles and the control volume are, respectively, one or more aircraft and a landing zone inducing a first airspace above the landing zone, one or more ground vehicles and an area of terrain including a second airspace above the terrain, one or more surface watercraft and a region of open water including a third airspace above the open water, one or more submersible watercraft and a volume of navigable water, or one or more spacecraft and a volume of navigable space.
