A system for use with an excavator of the type having a chassis, bucket support elements including a boom extending from the chassis and a dipper stick pivotally mounted on the end of the boom, and an excavator bucket pivotally mounted on the end of the dipper stick, determines the position of the excavator bucket during operation of the excavator at a worksite. The system includes a plurality of fixed ranging radios that are positioned at known locations at the worksite. A pair of ranging radios is mounted on the chassis of the excavator. A third ranging radio is mounted on one of the bucket support elements. A measurement circuit is responsive to the pair of ranging radios and to the third ranging radio, and determines the position and orientation of the excavator chassis, the bucket support elements, and the bucket with respect to the plurality of fixed ranging radios.
