The basic fluxgate compass is a simple electromagnetic device that employs two or more small coils of wire around a core of highly permeable magnetic material, to directly sense the direction of the horizontal component of the Earth's magnetic field.
A modern military compass, with included sight device for aligning. A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north.
An eCompass or e-Compass is a tilt compensated electronic compass utilizing an accelerometer and a magnetometer. A number of manufacturers, including Motorola, AKM Semiconductor, NXP, Bosch Sensortec, and ST micro make eCompasses. eCompasses are also found in some laptops such as the HP Spectre. Today's smartphones often include an eCompass ...
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 north. [3] This in turn links to a compass readout to provide a heading. [4] It has very high reliability and requires little maintenance during its service life. [4]
