NAVIGATION AND POINTING SYSTEM AND METHOD FOR CALIBRATING A NAVIGATION AND POINTING SYSTEM

The invention relates to a method of calibrating a navigation and pointing system (10) comprising a navigation unit (11) rigidly connected to a pointing device (12), the navigation unit being configured to measure the orientation of a navigation frame (21), the pointing device (12) being configured to measure a signal in a pointing frame (22). The calibration method comprises the following steps: - selecting a first plane surface (8) and a second plane surface (9); - acquiring measurements by means of the system by orienting the pointing direction towards the first plane surface (8), and respectively towards the second plane surface (9), according to a plurality of predetermined orientations; - applying a processing algorithm to the measurements acquired in the previous step in order to extract the misalignment angles between the navigation frame (21) and the pointing frame (22).
