Although Artillery rockets suffered a lack of accuracy in its aiming, proportional to its range, the introduction of GNSS and Inertial sensors allowed to overcome this problematic. Nevertheless, some issues remained due to its highly non-linear dynamics (fast spinning, inertia coupling), causing errors on attitude and position determination during terminal stages. We propose in this paper the addition of a low-cost sensor (quadrant photo-detector) and a hybridization of its information with the former ones, so this terminal guidance is achieved satisfactory. These results are tested over a rocket realistic flight model that is validated and fully detailed in the paper. |
