Abstract
A method for retrofitting a plurality of position sensors on a machine includes installing the plurality of position sensors on the machine, wherein the position sensors include at least two inertial measurement units (IMUs). The method further includes calibrating orientation of the IMUs, obtaining measurements from the IMUs, determining relative differences between the measurements obtained from the IMUs, and processing the relative differences using a Kalman filter procedure to determine positional data of the machine.
