Floating-card compass with prismatic sight (bearing 220° through eyepiece). The marine hand compass, or hand bearing compass|hand-bearing compass as it is termed in nautical use, has been used by small-boat or inshore sailors since at least the 1920s to keep a running course or to record precise bearings to landmarks on shore in order to determine position via the resection technique.
USBL (ultra-short baseline, also known as SSBL for super short base line) is a method of underwater acoustic positioning.A USBL system consists of a transceiver, which is mounted on a pole under a ship, and a transponder or responder on the seafloor, on a towfish, or on an ROV.
Certain Magellan vehicle navigation systems are also Bluetooth-compatible for integration with mobile phones, and traffic upgradeable for real-time traffic information. The Maestro 4050 is the first portable vehicle navigation device to offer drivers the convenience of voice command capabilities.
A 8×42 compass monocular. There are also some models of monoculars/binoculars, with electric lighting or without, which by means of an hybrid optical system (some of them electronic-digital) allow the bearing marks to be viewed at the same time as the object is observed through its optical system.
It is sometimes part of a ship's set of compasses, which also include a conventional gyrocompass and a magnetic compass under SOLAS requirements for the ship to be fitted with compass systems. [2] The compass comprises a fibre optic gyroscope sensor that operates on the principle of the Sagnac effect which links to a computer and then locates ...
Electronic compass can refer to: magnetometer (as in some hand-held GPS units) fibre optic gyrocompass (as in a ship's navigation system)
An early use of underwater acoustic positioning systems, credited with initiating the modern day development of these systems, [15] involved the loss of the American nuclear submarine USS Thresher on 10 April 1963 in a water depth of 2560m. [16] An acoustic short baseline (SBL) positioning system was installed on the oceanographic vessel USNS ...
In marine navigation, a pelorus is a reference tool for maintaining bearing of a vessel at sea. It is a "simplified compass" without a directive element, suitably mounted and provided with vanes to permit observation of relative bearings. [1] The instrument was named for one Pelorus, said to have been the pilot for Hannibal, circa 203 BC.
