LORAN-C Transmitter Seneca
The LORAN-C transmitter Seneca was the master station of the Northeastern United States LORAN-C Chain (GRI 9960) and the X-Ray secondary station of the Great Lakes Chain (GRI 8970). It was located within the Seneca Army Depot in Romulus, New York, south of Geneva. It used a 1000-kilowatt, 742-foot (226.2 m) guyed mast that was constructed in 1977 and dedicated on August 2, 1978. The station was operated by United States Coast Guard and was located on a 250-acre (1.0 km2) piece of land within the 10,587-acre (42.84 km2) facility. The transmitter was used to guide ships and aircraft up to 1,000 miles (1,600 km) away. It was the first LORAN station to use solid-state electronics versus vacuum tube components. The station, was shut down for good on February 9, 2010 at 3:00 p.m. EST. The tower was dismantled shortly after decommissioning of the LORAN-C system and was stacked in pieces next to the transmitter building awaiting further disposition. External links * ...

LORAN
LORAN, short for long range navigation, was a hyperbolic radio navigation system developed in the United States during World War II. It was similar to the UK's Gee system but operated at lower frequencies in order to provide an improved range up to with an accuracy of tens of miles. It was first used for ship convoys crossing the Atlantic Ocean, and then by long-range patrol aircraft, but found its main use on the ships and aircraft operating in the Pacific theater during World War II. LORAN, in its original form, was an expensive system to implement, requiring a cathode ray tube (CRT) display. This limited use to the military and large commercial users. Automated receivers became available in the 1950s, but the same improved electronics also opened the possibility of new systems with higher accuracy. The U.S. Navy began development of Loran-B, which offered accuracy on the order of a few tens of feet, but ran into significant technical problems. The U.S. Air Force worked on a ...

Northeastern United States
The Northeastern United States, also referred to as the Northeast, the East Coast, or the American Northeast, is a geographic region of the United States. It is located on the Atlantic coast of North America, with Canada to its north, the Southern United States to its south, and the Midwestern United States to its west. The Northeast is one of the four regions defined by the U.S. Census Bureau for the collection and analysis of statistics. The region is usually defined as including nine U.S. states: Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont. The U.S. Census Bureau–defined region of the Northeastern United States has a total area of with of that being land mass, making it the smallest region of the United States by both land mass and total area. The Northeastern region is the nation's most economically developed, densely populated, and culturally diverse region. Of the nation's four census regions, the No ...

Seneca Army Depot
The former Seneca Army Depot occupied between Seneca Lake and Cayuga Lake in Seneca County, New York. It was used as a munitions storage and disposal facility by the United States Army from 1941 until the 1990s. The Depot was listed in the 1995 Base Realignment and Closure Commission and formally shut down in 2000. The property has since been transferred to the Seneca County Industrial Development Agency, which leases it to Seneca County Economic Development Corp. Home to the world's largest herd of white deer, the base is in the towns of Varick and Romulus. Adjacent to the storage facility is the now-closed Seneca Army Airfield, whose long runway could handle large cargo aircraft. History During the 1940s, the Army stored radioactive materials in connection with the Manhattan Project in igloos E0801 through E0811, on the south end of the Depot. Despite no formal confirmation from the Department of Defense, it is known that during the cold war the depot held the larges ...

Guyed Mast
A guyed mast or guyed tower is a tall thin vertical structure that depends on guy lines (diagonal tensioned cables attached to the ground) for stability. The mast itself has the compressive strength to support its own weight, but does not have the shear strength to stand unsupported. It requires guy lines to stay upright and to resist lateral forces such as wind loads. Guy lines are usually spaced at equal angles about the structure's base. Guyed masts are used for telecommunications, sailing, and meteorology. The tallest guyed mast in the world is currently the KVLY-TV mast near Blanchard, North Dakota, USA. Two subtypes exist. A ''partially guyed tower'' is a structure consisting of a guyed mast on top of a freestanding tower. The guys may be anchored to the top of the freestanding structure, or to the ground. A famous tower of this type is the Gerbrandy Tower. An ''additionally guyed tower'' is a freestanding tower which either has guys attached temporarily to add stab ...

Solid-state Electronics
Solid-state electronics means semiconductor electronics: electronic equipment using semiconductor devices such as transistors, diodes and integrated circuits (ICs). The term is also used as an adjective for devices in which semiconductor electronics that have no moving parts replace devices with moving parts, such as the solid-state relay in which transistor switches are used in place of a moving-arm electromechanical relay, or the solid-state drive (SSD) a type of semiconductor memory used in computers to replace hard disk drives, which store data on a rotating disk. History The term "solid-state" became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology based on the transistor, in which the electronic action of devices occurred in a solid state, from previous electronic equipment that used vacuum tubes, in which the electronic action occurred in a gaseous state. A semiconductor device works by controlling an electric current ...

Vacuum Tube
A vacuum tube, electron tube, valve (British usage), or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric voltage, potential difference has been applied. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental electronic functions such as signal amplifier, amplification and current rectifier, rectification. Non-thermionic types such as a vacuum phototube, however, achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light intensities. In both types, the electrons are accelerated from the cathode to the anode by the electric field in the tube. The simplest vacuum tube, the diode (i.e. Fleming valve), invented in 1904 by John Ambrose Fleming, contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—fro ...

Military Facilities In New York (state)
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ...

LORAN-C Transmitters In The United States
Loran-C is a hyperbolic navigation, hyperbolic radio navigation system that allows a receiver to determine its position by listening to low frequency radio signals that are transmitted by fixed land-based Transmitter, radio beacons. Loran-C combined two different techniques to provide a signal that was both long-range and highly accurate, features that had been incompatible. Its disadvantage was the expense of the equipment needed to interpret the signals, which meant that Loran-C was used primarily by militaries after it was introduced in 1957. By the 1970s, the cost, weight and size of electronics needed to implement Loran-C had been dramatically reduced because of the introduction of solid-state electronics and, from the mid-1970s, early microcontrollers to process the signal. Low-cost and easy-to-use Loran-C units became common from the late 1970s, especially in the early 1980s, and the earlier LORAN system was discontinued in favor of installing more Loran-C stations around ...

Buildings And Structures In Seneca County, New York
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ...
