Abstract
In this work two Vehicle Equipment Bay (VEB) mass estimation models are applied to the estimation of the mass of the Ariane 5G VEB. The two models presented include a low-level (level 0) and an intermediate level (level 1) fidelity model. The low-level model provides a Most Likely Estimate (MLE) of 1118 kg compared to a "true" value in range 1430 to 1500 kg. The intermediate level model provides an MLE of 1506 kg and shows a clear improvement in the estimated mass as compared to the true mass. It is advised though to further investigate the validity of the two models used with focus on the intermediate level model as it seems better capable of providing the required accuracy.
