OPTICAL NAVIGATION AID WITHIN A BEACON FIELD
First Claim
1. A secondary optical system for object navigation in an array of beacons comprising:
- an optical source having at least one optical emitter emitting an optical signal and mounted to either the moving object or a beacon of the array of beacons, the moving object in simultaneous radio frequency communication with at least two beacons of the array of beacons to determine dynamic position of the object;
an optical detector mounted to the other of a moving object or the beacon of the array of beacons relative to said optical source, said optical detector receiving the optical signal when line of sight exists between the moving object and a beacon of the array of beacons; and
electronics for determining the dynamic position of the moving object uses weighting factor that favors the communication and at least two beacons of the array of beacons for which a moving object-beacon optical line of sight exists.

Abstract
A secondary optical system for object navigation in an array of beacons is provided that includes an optical source having at least one optical emitter emitting an optical signal and that is mounted to either the moving object or a beacon of the array of beacons. The moving object in simultaneous radio frequency communication the array of beacons to determine dynamic position of the object. An optical detector is mounted to the other of a moving object or the beacon of the array of beacons and the optical detector receives the optical signal when line of sight exists between the moving object and a beacon of the array of beacons. Electronics are provided for determining the dynamic position of the moving object uses weighting factor that favors the communication and at least two beacons of the array of beacons for which a moving object-beacon optical line of sight exists.

14. A process for object navigation in an array of beacons comprising:
-
deploying an array of beacons, each with an optical source comprising an optical emitter, emitting an optical signal, or an optical detector for detecting the optical signal; operating a moving object within the array of beacons, the moving object deploying the other of said optical source or said optical detector relative to the array of beacons; and computing a dynamic position of the moving object based on radio frequency communication between the object and at least two of the beacons of the array based on a weighting factor in favor of beacons for which moving object-beacon optical line of sight exists. - View Dependent Claims (15, 16, 17, 18)
