| Глоссарий по геодезии |
- Прибор измерения азимута магнитного на местности. основные части: магнитная стрелка, кольцо с угловыми делениями и диоптры для наведения на предмет. в
- (франц . boussole), инструмент для измерения магнитного азимута направлений на местности. применяют при геодезических работах, в маркшейдерии; в артиллерии - при управлении огнем.

Compass, английский
- Compatible assembly system
- Navigational instrument showing the direction of the vessel in relation to the earth`s geographical poles or magnetic poles. commonly consists of a magnet aligned with the earth`s magnetic field, but other technologies have also been developed, such as the gyrocompass.
- Буссоль, компас
- An instrument for drawing circles, measuring the distance between two points, etc.; consists of two pointed legs, movable on a joint or pivot, usually made so that one of the points can be detached for the insertion of a pen, extension, etc.
- Компас
- The magnetic instrument which indicates the direction in which the boat is headed. coin pass rose. the circles on a chart which indicate the direction of true and magnetic north.
- An instrument employed by navigators to guide the ship`s course at sea. it consists of a circular box, containing a fly or paper card, which represents the horizon, and is suspended by two concentric rings called gimbals. the fly is divided into thirty-two equal parts, by lines drawn from the centre to the circumference, called points or rhumbs; the interval between the points is subdivided into 360 degrees—consequently, the distance or angle comprehended between any two rhumbs is equal to 11 degrees and 15 minutes. the four cardinal points lie opposite to each other; the north and south
- A direction-finding instrument showing the heading of a ship. magnetic compasses orient themselves to the earth’s magnetic field and can only show magnetic north. a gyrocompass depends on the tendency of freely-spinning rotors to maintain spatial orientation, and can be set to indicate true north.
- A maas or other compass device used in borehole-survey work.
- An instrument for determining directions, usually by a device having a magnetic needle free to turn in a horizontal plane.
- Буссоль, компас beam ~ штангенциркуль
- Combined performance and safety system
Magnetic compass, английский
- The most common liquid-type compass, capable of calibration to compensate for magnetic influences within the aircraft.
- Магнитный компас
- Буссоль, магнитный компас
- A compass using a magnetic needle or card which points in the direction of the north magnetic pole. the “flux-gate” version enhances its features by employing small coils of wire wound around a magnetic core to directly sense the horizontal component of the earth‘s magnetic field, providing readings in electronic form that can be digitized and used by an autopilot for course correction. readout may also be analogue. the principle of magnetism was known in china as early as the third century bce, and the compass itself was probably invented there during the ninth century of the current era. its use for navigation is first mentioned by zhu yu in 1119; “the navigator knows the geography, he watches the stars at night, watches the sun at day (but) when it is dark and cloudy, he watches the compass.” seventy years later, the compass had appeared in europe but it is unclear whether it was transferred from china or invented independently. the latter is likely because european instruments used a different number of compass points, and the needle indicated north, whereas the chinese version pointed south. in an unusual reverse direction of technology transfer, arabs—who call the instrument al-konbas—seem to have adopted the european design.
