What is another word for inertial guidance?
Pronunciation: [ɪnˈɜːʃə͡l ɡˈa͡ɪdəns] (IPA) 
Inertial guidance refers to a method that uses a device called an inertial navigation system (INS) to determine and track the position, orientation, and velocity of a moving object. Some common synonyms for inertial guidance include inertial navigation, inertial guidance system, or simply INS. INS relies on a set of gyroscopes and accelerometers to measure the movement of the system and ultimately guide it to the desired destination. Other similar systems that are commonly grouped with inertial guidance include GPS (Global Positioning System) and celestial navigation. These systems all provide ways to determine direction and movement for objects in motion, providing useful information for a variety of practical applications from aircraft flying to missile guidance.
