Zusammenfassung:	A method of calibration of a navigation and pointing system (10) including a navigation unit (11) integrally connected to a pointing device (12), the navigation unit being configured to measure the orientation of a navigation reference system (21), the pointing device (12) being configured to measure a signal in a pointing reference system (22). The calibration method includes the following steps: selecting a first planar surface (8) and a second planar surface (9); acquiring measurements via the system by directing the pointing direction towards the first planar surface (8), and respectively towards the second planar surface (9), according to a plurality of predetermined orientations; applying an algorithm for processing the measurements acquired at the previous step to extract therefrom the misalignment angles between the navigation reference system (21) and the pointing reference system (22).
