Patent ID: 7983694

Claim:
A target comprising: a transceiver for transmitting and receiving signals; a central processing unit for performing operations; a power source for powering the transceiver and the central processing unit; and software executed by the central processing unit for diagnosing and managing the target, and for calculating position of the target using range measurements to and between a plurality of base stations; wherein the plurality of base stations is initialized to determine their relative locations to each other wherein, during initializing, a first base station of the plurality of base stations sends an ultra wideband signal to a second base station and a third base station of the plurality of base stations to determine a distance between the first base station and the second base station and a distance between the first base station and the third base station and wherein the second base station sends an ultra wideband signal to the third base station to determine a distance between the second base station and the third base station; wherein the target determines range measurements by measuring the time of arrival or the time difference of arrival of the signals from the plurality of base stations, and the target calculates directly the location of the target relative to the plurality of base stations.
