The mathematical modelof reentry maneuvering trajectory is established. The fitting expression of aerodynamic coefficient function on velocity, attack of Angle and altitude is presented.
The result also reveals that B-spline model performs better than other models integralively in precision offitting prices, curve smoothness and stability.
