    Abstract: A method of determining a heading of a machine having an implement is provided. The method includes determining a first heading data of the machine using an inertial sensor. The method includes determining a second heading data of the machine using a magnetometer. The method includes determining a position of the implement in a stationary state. The method also includes calculating a corrected second heading data based on a predefined relation between the position of the implement in the stationary state and the second heading data. The method further includes determining the heading of the machine based on the first heading data and the corrected second heading data.

    Abstract: A system having a primary inertial measurement unit and a secondary inertial measurement unit configured to generate a primary position signal and a secondary position signal respectively is provided. The system also includes an error detection module communicably coupled to the primary inertial measurement unit and the secondary inertial measurement unit. The error detection module is configured to receive the primary position signal and the secondary position signal and detect if an out-range error is present in at least one of the primary position signal and the secondary position signal. The error detection module is also configured to detect if an in-range error is present in at least one of the primary position signal and the secondary position signal and determine an action to be performed based on the presence of at least one of the out-range error and the in-range error.
