Backsight, traverse, and solar observation are no longer required for seeking true north when GYRO X II is on the job. It operates anywhere, anytime, where other technologies cannot work or when no known station is available.
GYRO X II uses a suspended gyromotor that oscillates around the earth's meridian (true north) due to the principle of precession caused by the rotation of the earth. This principle realizes faster and more precise measurement than other solutions.
