It has radar, communication, satellite navigation, gyrocompass
, GPS and other systems.
On 21 March 1919, a gyrocompass
developed for the Navy was tested in an aircraft, marking the first recorded instance of tests of a device that would become an invaluable navigational instrument for long-range flight.
There's the German company Anschutz, a division of Raytheon, which makes autopilot and gyrocompass
equipment; the British firm Brooks & Gatehouse, a division of Yeoman Group, that sells instrument systems and software; and Northstar Technologies of Acton, MA, for global positioning systems.
A professional ethic is a gyrocompass
pointing in a precalibrated direction.
What is necessary is to provide for the dynamics of direction in the form of a gyrocompass
Of course, other technologies must be considered as well: Hemispheric Resonant Gyroscopes (HRGs) are making progress and are now designed for navigation; Coriolis vibrating piezo gyroscopes are finding increasing success in a large variety of end-markets while new disruptive gyro technologies are still in lab-phase; and finally, DTG and other mechanical gyro technologies are still used in some retrofit systems for 2-axis stabilization systems or for gyrocompass
, but this trend points to a decline.
DARTMOUTH, Nova Scotia, April 27, 2015 /PRNewswire/ -- Northrop Grumman Corporation's (NYSE: NOC) Sperry Marine business unit has been selected to design and supply gyrocompass
navigation systems for 12 Kingston Class coastal defence vessels for the Royal Canadian Navy, as a subcontractor to SNC-Lavalin Defence Programs Inc.
Meanwhile, shipborne or submarine sonars, from single beam to multi-beam echo sounders combining sensor swathe with attitude sensors, gyrocompass
, and inertial navigation, deliver bathymetric information to map deep seafloor features.
Sperry invented the first marine gyrocompass
in 1908 and earned more than 350 patents during his career in the maritime industry.
The direction of the tunnel measured from true north was first measured precisely on the ground surface with the gyrocompass
and a theodolite survey instrument.
