a guidance system for an aerospace vehicle, in which self-contained devices determine the vehicle’s course on the basis of the directions and magnitudes of the accelerations it undergoes in flight.
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
noun, Physics. 1. the mass of a body as determined by the second law of motion from the acceleration of the body when it is subjected to a force that is not due to gravity. 2. the measure of the property of inertia. Compare , (def 2a), . noun 1. the mass of a body […]
- Inertial observer
noun 1. a hypothetical observer who is not accelerated with respect to an inertial system. Newton’s laws of motion and the special theory of relativity apply to the measurements which would be made by such observers
noun, Navigation. 1. self-contained navigational devices used in inertial guidance, along with their mounting.
noun, Physics. 1. a frame of reference in which a body remains at rest or moves with constant linear velocity unless acted upon by forces: any frame of reference that moves with constant velocity relative to an inertial system is itself an inertial system. noun 1. a frame of reference within which bodies are not […]
