Abstract:
A system and method for determining the range, angle, and elevation of a target object having a radio transceiver relative to a known location is provided. The system includes a primary radio transceiver located an initially unknown distance from the target object, and at least one auxiliary radio receiver located a known distance and angle relative to a reference bearing from the primary radio transceiver. The system further includes a processing unit in communication with the primary radio transceiver and at least one auxiliary receiver. The processing unit is capable of calculating the range between the primary and the target object and the angle to the target object relative to the reference bearing. The method includes the steps of: (1) acquiring range data between at least a primary radio transceiver of the system and the target object using two way ranging; (2) transmitting the range data to a processing unit that is in communication with the primary radio transceiver and at least one auxiliary radio receiver; (3) calculating the range between the primary radio transceiver and the target object using two way ranging algorithms at the processing unit; (4) acquiring time of arrival data for signals exchanged between the target object and the at least one auxiliary radio receiver; and (5) determining the angle of the target object relative to a reference bearing from the primary radio transceiver of the system by running the time of arrival data from the tracked object through an algorithm.

Claim (Index 8):
A method for determining the range and direction of a target object relative\n to a known location comprising the steps of:\n a. acquiring timing data of transmit and receive times of packets between at least a primary radio transceiver located in a first known coordinate location and the target object; \n b. calculating a first distance (d tp ) between the primary radio transceiver and the target object based on the acquired timing data using two way ranging algorithms; \n c. acquiring time of arrival data for signals exchanged between the target object and said primary radio transceiver and between the target object and each of a plurality of auxiliary radio receivers positioned at a known coordinate location relative to the primary radio transceiver; \n d. selecting an arbitrary point x n  on an arc located at the first distance (d tp ) from the primary radio transceiver; \n e. computing the estimated time of arrival data for signals between the arbitrary point x n  and said primary radio transceiver and between the arbitrary point x n  and each of said plurality of auxiliary radio receivers based on the known coordinate location of the arbitrary point x n, , the known coordinate location of the primary radio auxiliary radio receivers; \n f. comparing the actual measured time of arrival data for the target object to the estimated time of arrival data for the arbitrary point x n ; \n g. determining whether the estimated time of arrival data for the arbitrary point x n  is within an acceptable margin of error to the actual measured time of arrival data for the target object; \n h. if the estimated time of arrival data for the arbitrary point x n  is not within the acceptable margin of error, selecting a further arbitrary point x n+1  along the arc. \n i. repeating steps e-h for each further arbitrary point x n+1  until an acceptable margin of error is reached.
