The M58 mine-clearing line charge (MICLIC) is a rocket -projected mine-clearing line charge used to provide a "close-in" demining capability for maneuver forces of the United States Army and Marine Corps. [1][2][3] First fielded in 1988 with United States Army Europe, [4] the MICLIC is a cable fitted with explosive charges.
The history of longitude describes the centuries-long effort by astronomers, cartographers and navigators to discover a means of determining the longitude of any given place on Earth. The measurement of longitude is important to both cartography and navigation. In particular, for safe ocean navigation, knowledge of both latitude and longitude ...
naval ships, aircraft and land-based missile launchers. The RBS 15 (Robotsystem 15) is a long-range fire-and-forget surface-to-surface and air-to-surface anti-ship missile. The later version Mk. IV has the ability to attack land targets as well. The missile was developed by the Swedish company Saab Bofors Dynamics.
Radio navigation. Radio navigation or radionavigation is the application of radio waves to determine a position of an object on the Earth, either the vessel or an obstruction. [1][2] Like radiolocation, it is a type of radiodetermination. The basic principles are measurements from/to electric beacons, especially.
The compass was invented in China during the Han dynasty between the 2nd century BC and 1st century AD where it was called the "south-governor" (sīnán 司南) or "South Pointing Fish" (指南魚). [3] The magnetic compass was not, at first, used for navigation, but for geomancy and fortune-telling by the Chinese.
Direction finding antenna near the city of Lucerne, Switzerland. Direction finding (DF), or radio direction finding (RDF), is the use of radio waves to determine the direction to a radio source. The source may be a cooperating radio transmitter or may be an inadvertant source, a naturally-occurring radio source, or an illicit or enemy system.
TERCOM. Terrain contour matching, or TERCOM, is a navigation system used primarily by cruise missiles. It uses a contour map of the terrain that is compared with measurements made during flight by an on-board radar altimeter. A TERCOM system considerably increases the accuracy of a missile compared with inertial navigation systems (INS).
A local positioning system (LPS) is a navigation system that provides location information in all weather, anywhere within the coverage of the network, where there is an unobstructed line of sight to three or more signaling beacons of which the exact position on Earth is known. [2][3][4][5] Unlike GPS or other global navigation satellite ...
