The sensors used in FEBE were based on Marine gyrocompasses
and the gyroscopic elements of Doc's World War II anti-aircraft fire control systems.
Teledyne TSS Limited, a leading player in the marine navigation, gyrocompasses
and steering controls based in UK, has appointed Unique Systems as its authorized service provider for the UAE.
The credit union's roots trace back to iconic inventor Elmer Ambrose Sperry (1860-1930), who introduced the world's first ballistic gyrocompass
system in 1908.
The accuracy of this method is based on instrumentation and includes the use of a gyrocompass
and hydrostatic water level to help guide the AVN machine and product pipe to their destination by monitoring vertical depths and horizontal deviations.
While most aircraft have at least two compasses, a gyrocompass
and a magnetic compass, they are fixed to the aircraft and not helpful measuring angles without making s-turns.
He also discusses specific works like Feuille de route; his inventions, including the navigational gyrocompass
; and his military career.

Therefore, Liebisch designed a special delicate device: the crystal is mounted with beeswax onto a small disc which is suspended within a pair of gimbaled rings similar to the attachment of a gyrocompass
. This arrangement assures a gentle and proper contact between crystal and prism for all settings.
An example of integrating a terrestrial scanning system, a system which is used in investigating the underwater pipeline from the oil field of the continental shelf of the Black Sea, contains the most important components on hydrographical scanning: RTK positioning system, motion sensor, gyrocompass
, well for measuring the speed of sound, mono fascicule and multi fascicule well, the unit for synchronization in time, the onboard computers and software for navigation and the hydrographical data acquisition (Plopeanu, 2008).
Occupying a critically important space between its ancestral roots (the primitive lodestone) and its late 20th-century descendents (the gyrocompass
and GPS technology), the magnetic compass, born of the need for a reliable means of negotiating treacherous sea routes around the globe, has been an indispensable sailor's guide.
