Minuteman II NS17 Missile Guidance Set
The Boeing LGM-30F Minuteman II Intercontinental Ballistic Missile (ICBM) relied on this all-inertial NS17 Missile Guidance Set (MGS) for accurately navigating to its target thousands of miles away. The MGS, originally designed and produced by the Autonetics Division of North American Aviation, could store multiple preprogrammed targets in its internal memory.
Unlike other methods of navigation, inertial guidance does not rely on observations of land positions or the stars, radio or radar signals, or any other information from outside the vehicle. Instead, the inertial navigator provides the guidance information using gyroscopes that indicate direction and accelerometers that measure changes in speed and direction. A computer then uses this information to calculate the vehicle's position and guide it on its course. Enemies could not "jam" the system with false or confusing information.
The Ogden Air Logistics Center at Hill AFB has been Program Manager for the Minuteman ICBM family since January 1959. The base has had complete logistics management responsibilities for Minuteman and the rest of the ICBM fleet since July 1965.
