The effectiveness of aero control decreases as dynamic pressure decreases. Therefore impulse attitude control motor(ACM) is to be used to maintain fast response of missile in low dynamic pressure.
This paper provides a method for determining the optimum time and attitude in process of geostationary satellite launch at which the solid-apogee motor to be fired.
