Abstract
Systems and methods for augmenting an inertial navigation system (INS) include outputting from the INS position information associated with the implement and adjusting the implement based upon a comparison of the position information of the implement and a desired position of the implement. The INS is periodically re-initialized using error estimates generated by a kalman filter as a function of position information from one or more positioning (or measuring) devices, such as a fan laser, an automatic total station (ATS), a GNSS receiver, or a ground based radio positioning system, to correct a drift of the position information that may be caused by inherent characteristics of the INS.
