1. A sensor calibration system for a mobile machine, comprising:

  • a positioning device configured to determine a desired sensing location on the mobile machine;

    a calibration object;

    a sensor configured to sense a characteristic of the calibration object from an actual sensing location on the mobile machine and to generate a corresponding signal; and

    a controller in communication with the sensor and the positioning device, the controller being configured to;

    compare the characteristic sensed from the actual sensing location to a known characteristic previously sensed from the desired sensing location;

    determine a difference between the actual sensing location and the desired sensing location based on the comparison; and

    correcting subsequent signals generated by the sensor based on the difference.
