Ultra-wideband radio frequency tracking of an implement on a work vehicle relative to a main body of the work vehicle

A positioning system for an implement on a work vehicle, the system comprising:

• a first radio frequency (RF) device mounted at a fixed location relative to the implement;
• at least one additional RF device mounted at a fixed location relative to a main body of the work vehicle, wherein the implement of the work vehicle is controllably movable relative to the main body of the work vehicle;
• and
• an electronic controller communicatively coupled to the first RF device and the at least one additional RF device, the electronic controller configured to
• determine a position of the first RF device relative to a local reference frame using ultra-wideband ranging between the first RF device and the at least one additional RF device, wherein the local reference frame is fixed relative to the main body of the work vehicle, and
• determine a position and an orientation of the implement relative to the local reference frame while the work vehicle is in motion based at least in part on the determined position of the first RF device relative to the local reference frame,
• wherein a power amplitude of the ultra-wideband ranging is configured to provide a tracking range that is less than a length of the work vehicle, and wherein the ultra-wideband ranging is configured such that a decrease in the tracking range results in a corresponding increase in a tracking accuracy.
