Zusammenfassung:	Methods and apparatus are provided for calibrating and initializing/aligning an attitude and heading reference system of a crane (110) jib. Magnetometer measurements are generated using a magnetometer (204) that is attached to the crane jib, while crane jib maneuvers are performed including crane jib slewing. The magnetometer measurements are supplied to a processor (210) that is configured to generate magnetometer calibration parameters using the magnetometer measurements and to initialize and align a plurality of filters.
