WebA one degree of freedom gyro rotor that has drift typically used in ships and aircraft since it's more accurate than a simple magnetic compass. The magnetic compass has a big error if it's not held horizontally or near metal or wires carrying electrical currents. Totally inoperable in a metal submarine or armored tank. WebThe Perfect Tool for Gyroscopic Surveying. Our GYROMAT 5000 is the most accurate surveying gyroscope in the world. Its measurement method compensates for possible sources of error such as refraction, error …

Use of the environment. ambient temperature In surveying, a gyrotheodolite (also: surveying gyro) is an instrument composed of a gyrocompass mounted to a theodolite. It is used to determine the orientation of true north. It is the main instrument for orientation in mine surveying and in tunnel engineering, where astronomical star sights are not visible and … See more In 1852, the French physicist Léon Foucault discovered that a gyro with two degrees of freedom points north. This principle was adapted by Max Schuler in 1921 to build the first surveying gyro. In 1949, the gyro … See more A gyroscope is mounted in a sphere, lined with Mu-metal to reduce magnetic influence, connected by a spindle to the vertical axis of the … See more Although a gyro-theodolite functions at the equator and in both the northern and southern hemispheres, it cannot be used at either the North Pole or South Pole, where the Earth's axis is precisely perpendicular to the horizontal axis of the spinner and the … See more Gyro-theodolites are primarily used in the absence of astronomical star sights and GPS.
