gyroscopic compass

Because of this tendency, most ships and airplanes use gyroscopic compasses instead.

Due to its high density, this material is found in inertial guidance systems and in gyroscopic compasses.

Elmer Ambrose Sperry, prolific inventor who invented gyroscopic compass and held over 400 patents.

A magnetic compass (as opposed to a gyroscopic compass) consists of a small, lightweight magnet balanced on a nearly frictionless pivot point.

The next advance was in the modification of small gyroscopic compasses by the Sperry Corporation, which was making similar compasses for aeronautical navigation.

Sperry experimented with diesel engines and gyroscopic compasses and gyroscopic stabilizers for ships and aircraft.

San Marco was the first ship to feature a gyroscopic compass, the first ship with anti-rolling water tanks, and the first turbine-fitted ship with four propellers.

S. G. Brown Ltd was established in 1903 by British engineer Sidney George Brown, to manufacture scientific instruments, its best known product was the gyroscopic compass.

Between the wars he trialled the first gyroscopic compass for aircraft in the RAF and became Air attaché to Turkey in the run up to World War II.

Sperry in Britain started with a factory in Pimlico, London in 1913, manufacturing gyroscopic compasses for the Royal Navy, and becoming the Sperry Gyroscope Co Ltd in 1915.

On 21 June, while the ship was undergoing a refit at Shewan's Shipyard, Brooklyn, Elmer A. Sperry, the inventor of the gyroscopic compass, came on board to work on one of his compasses that had been installed in the ship.

During the First World War, he and his son, Harold, were working on an aeroplane engine which received favorable comment from the National Advisory Committee for Aeronautics and engineers such as Elmer Sperry, the inventor of the gyroscopic compass and stabilizing devices.
