Abstract: This paper presents the latest results of the experimental validation of the computational model of the proposed Data Processing Unit (DPU) for the Vigil mission using modal analysis and forced vibration. Several geometric modifications were performed, including changes to both the frame and the shielding baffles, in order to find the optimum design that would result in the desired reduction in deflections during booster launch. The final designed geometry of the DPU unit was subjected to all the prescribed calculations required for its certification.
