Ranging radio relative machine positioning system and method

Abstract:

A ranging radio relative machine positioning system for a first mobile machine and a second mobile machine is provided. The first mobile machine includes a platform rotatable relative to ground-engaging elements of the first mobile machine. A first set of ranging radios and at least one sensor are configured for attachment to the first mobile machine, and a second set of ranging radios are configured for attachment to the second mobile machine. The system also includes a controller programmed to identify a ground spotting location relative to the first mobile machine, track movement of the first mobile machine relative to the ground spotting location using the sensor to arrive at an offset, and provide a location, or pose, of the second mobile machine relative to the ground spotting location using the first and second sets of ranging radios and the offset.
