  Due to advances in cold atom interferometry, laser spectroscopy it is
possible to achieve more precise accelerometers and gyroscopes which never
occurs in mechanical- and optical-based sensors. Because of the inherent and
independent characteristics of atomic levels which are too sensitive respect to
the external changes, a self-calibrated navigation system with no satellite can
be achieved. Here, in this paper we very shortly review the basic principles of
inertia cold atom navigation sensor.
