<p>The present invention relates to a simulation system comprising at least one virtual projectile/missile firing device associated to a determined position and having movable directing means arranged to direct a virtual projectile/missile towards a target and means (4) arranged to capture at least one image of the scene in front of the directing means. The simulation system is characterized in that it comprises a terrain database (11) with the positions of landmarks marked, in that it comprises processing means (15) arranged to process the image of the scene so as to identify at least one landmark of the terrain database (11) in the image and in that said processing means (15) further are arranged to determine the compass bearing of the directing means based on at least the position of the virtual projectile/missile and the position of the identified at least one landmark.</p> |
