inertial guidance

n.
Guidance of an aircraft or spacecraft in which gyroscopic and accelerometer data are used by a computer to maintain a predetermined course. Also called inertial navigation.

inertial guidance

or

inertial navigation

n
(Firearms, Gunnery, Ordnance & Artillery) a method of controlling the flight path of a missile by instruments contained within it. Velocities or distances covered, computed from the acceleration measured by these instruments, are compared with stored data and used to control the speed and direction of the missile. Compare celestial guidance, terrestrial guidance

iner′tial guid′ance


n.
an on-board system that determines an aerospace vehicle's course by means of devices, as a gyroscope and accelerometer, that measure the accelerations of the vehicle in flight. Also called iner′tial naviga′tion.
[1950–55]

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.
