gyrocompassing

[′jī·rō‚käm·pəs·iŋ]
(navigation)
In inertial navigation equipment, a process of self-alignment in azimuth accomplished without any external equipment, consisting basically of using the inertial platform's accelerometers to slave it to the local gravity vector, and employing one of the gyros to seek true north by sensing the rotation of the earth in the manner of a gyro compass.

This self-initialization technique is called gyrocompassing or northfinding , since the function of the compass is performed by gyros.
EMCORE's fiber optic gyro technology is designed for fast, accurate navigation and gyrocompassing, and low noise line- of-sight stabilization.
They also are applicable for gyrocompassing systems for naval vessels, ships, submarines, ROV, AUV, as well as guidance systems for strategic and tactical missiles.
