The V-2 rocket, developed by the Germans during World War II, is considered the world's first ballistic missile. It was guided to its target by a system of gyroscopes, which measured the acceleration of the rocket as it ascended from earth. Because the guidance system used only internal measurements, it could not be jammed or set off course, but it did require very precise gyroscopes and other devices. This talk will describe the workings of a V-2 guidance system, which is the ancestor of missile guidance systems in use today.
