ABSTRACT	arried out using the model at the pre-design phase of the HYFLEX.However,more precise flight analysis had to be carried out to predict the splash down point as we planned to recover the HYFLEX vehicle.In this paper,two coordinate systems were newly introduced to deal with the earth as a ellipsoid of revolution and new equations of motion were derived.Also,the gravity model was changed to the model mentioned in Reference 4.To maintain precision,two state vectors were newly defined.The designed navigation,guidaance and control system of the HYFLEX is proved to satisfy the mission requirements through the results of flight analysis.Further,more accurate data of the nominal impact point and dispersion of the impact point are obtained.
