The Lowcountry (sometimes Low Country or just low country) is a geographic and cultural region along South Carolina's coast, including the Sea Islands. The region includes significant salt marshes and other coastal waterways, making it an important source of biodiversity in South Carolina.
Currently manufactured by ThalesRaytheonSystems, the system is a long-range version of "weapon-locating radar", designed to detect and track incoming artillery and rocket fire to determine the point of origin for counter-battery fire. It is currently in service at brigade and higher levels in the United States Army and by other countries.
The Ground/Air Task Oriented Radar (G/ATOR) is a single material solution for the mobile Multi-Role Radar System and Ground Weapons Locating Radar (GWLR) requirements. It is a three-dimensional, short/medium-range multi-role radar designed to detect unmanned aerial systems, cruise missiles, air-breathing targets, rockets, artillery, and mortars.
Derrick (#14) is the support structure for the equipment used to lower and raise the drill string into and out of the wellbore. This consists of the sub-structure (structure below the drill floor level) and the mast. Desander / desilter (not pictured) contains a set of hydrocyclones that separate sand and silt from the drilling fluid. Typically ...
Avalanche transceivers operate on a standard 457 kHz, and are designed to help locate people and equipment buried by avalanches. Since the power of the beacon is so low the directionality of the radio signal is dominated by small scale field effects [15] and can be quite complicated to locate.
Further developments in the field remained sparse until the 1970s, when military applications began driving research. Commercial applications followed and the first affordable consumer equipment was sold in 1975. [4] In 1972, the Apollo 17 mission carried a ground penetrating radar called ALSE (Apollo Lunar Sounder Experiment) in orbit around ...
Osborne also designed the photo-recording transit for making panoramic records of forest conditions, as well as a collapsible water-bag knapsack for firefighting (patented in the US in 1935). Many fire finders were manufactured from 1920 through 1935, but the manufacturer, Leupold & Stevens, Inc., stopped production of replacement parts after 1975.
In low-threat environments, such as the Balkans in the 1990s, they may transmit continuously and deploy in clusters to provide all-around surveillance. In other circumstances, particularly counter-insurgency, where ground attack with direct fire or short range indirect fire is the main threat, radars deploy in defended localities but do not ...
