As I understand it, there is no guidance system as such on the first
stage. The launch rail is used to set the azimuth, and canted fins
provide a 150 rpm spin. Second and third stages have cold gas attitude
control systems that maintain a fixed attitude with the spin rate
decreased to less than 60 rpm.
