The space shuttle is steered using an on-board guidance controller which determines the desired attitude. The ascent autopilot uses the errors between the measured and determined target attitude through the angular position, velocity and accelerations to gimbal the space shuttle main engines and the solid rocket boosters to effect the desired vehicle attitude. A simplified version of the pitch controller is given below in Figure Q2.
