===Inertial reference===

The [[Inertial reference unit|IR]] component of an ADIRU gives attitudealtitude, flight path vector, ground speed and positional data.<ref name="art5" /> The [[ring laser gyroscope]] is a core enabling technology in the system, and is used together with [[accelerometer]]s, [[GPS]] and other sensors to provide raw data.<ref>{{cite book|url=https://books.google.com/books?id=5ShYAAAAMAAJ&pgis=1|title=International Aerospace Abstracts|publisher=Cambridge Scientific Abstracts, Inc, [[American Institute of Aeronautics and Astronautics]]|year=1985|accessdate=2008-10-16}}</ref> The primary benefits of a ring laser over older mechanical [[gyroscope]]s are that there are no moving parts, it is rugged and lightweight, frictionless and does not resist a change in [[precession]].
