Abstract
A method for determining a compensated first position of a linkage of a machine is disclosed. The method includes sensing a first position of the linkage, determining a first deflection value based on the sensed first position, and utilizing the sensed first position and the determined deflection value to calculate a compensated first position of the linkage. The method may be used for determining a compensated offset distance between a first and a second position of a linkage of a machine.
