A reliable and inexpensive attitude control system uses a plurality of pitch-over thrusters to perform rapid and precise attitude maneuvers for a flight vehicle. The pitch-over thrusters create rotational moments that directly pitch and yaw the flight vehicle. The use of very simple thrusters and control techniques provides for a reliable and cost effective solution. The ability to perform overlapping pitch and yaw maneuvers with single-shot fixed-impulse thrusters provides for high-speed maneuverability. Although this approach is applicable to provide a...
We claim: 1. An attitude control system for a flight vehicle, comprising:at least four thrusters on the flight vehicle and displaced from the vehicle center of gravity so that their thrust vectors produce rotational moments to directly pitch and yaw the flight vehicle; anda fire controller configured to operate open-loop to issue start firing commands to a first set of said thrusters to slew the flight vehicle and without measurement of the pitch and yaw as the vehicle slews to issue stop firing commands to a second set of said thrusters to stop the flig...
