inertial navigation

n

(Firearms, Gunnery, Ordnance & Artillery) a method of controlling the flight path of a missile by instruments contained within it.

inertial guidance

A guidance system designed to project a missile over a predetermined path, wherein the path of the missile is adjusted after launching by devices wholly within the missile and independent of outside information. The system measures and converts accelerations experienced to distance traveled in a certain direction.
