Method and system for the tracking of a moving object by a tracking device

Method for the tracking of at least one moving object by a tracking device, the tracking device comprising at least one tracking means mounted in an articulated manner on a fixed support, characterized in that it comprises a step of calibration of the tracking device comprising accelerometers, inclinometers or a compass, on the support or the tracking means, in order to determine the orientation of a reference peculiar to the support and/or to the tracking means with respect to the local vertical, or in the local geographic reference system and comprises at least the following steps:

• (a) reception by the tracking device of a signal transmitted by the moving object or objects and comprising a first item of information of the position of the moving object or objects determined from information received from a satellite positioning system,
• (b) determination of a second item of information of the relative altitude of the moving object or objects with respect to the tracking device, and the said second item of information is calculated on the basis of the atmospheric pressures measured at the altitude of the tracking device and on the moving object or objects,
• (c) calculation of the relative position of the moving object or objects with respect to the tracking means, from a mixture of the first and second items of information using a data fusion technique,
• (d) orientation of the tracking means towards the relative position calculated in step.
