gy·ro·com·pass

 (jī′rō-kŭm′pəs, -kŏm′-)
n.
A compass with a motorized gyroscope whose angular momentum interacts with the force produced by the earth's rotation to maintain a north-south orientation of the gyroscopic spin axis, thereby providing a stable directional reference.

gyrocompass

(ˈdʒaɪrəʊˌkʌmpəs)
n
(Navigation) nautical a nonmagnetic compass that uses a motor-driven gyroscope to indicate true north. Sometimes shortened to: gyro

gy•ro•com•pass

(ˈdʒaɪ roʊˌkʌm pəs)

n.
a navigational compass containing a gyroscope rotor that registers the direction of true north along the surface of the earth.

Of course, other technologies must be considered as well: Hemispheric Resonant Gyroscopes (HRGs) are making progress and are now designed for navigation; Coriolis vibrating piezo gyroscopes are finding increasing success in a large variety of end-markets while new disruptive gyro technologies are still in lab-phase; and finally, DTG and other mechanical gyro technologies are still used in some retrofit systems for 2-axis stabilization systems or for gyrocompass, but this trend points to a decline.
