The time history of the angle-of-attack for a re-entry vehicle is determined from knowledge of the angular rates about the body axes. The method presented utilizes Eulerian angle relationships between a moving set of body axes and a set of axes fixed with respect to inertial space. These equations are integrated to yield data defining the history of the rotational motion of the vehicle. A numerical filter is applied to this data to separate the motion due to the vehicle aerodynamic oscillation from the motion due to gravity and from the fictitious motion due to drift in the process of integration.
