Angissq LORAN-C Transmitter
Angissoq LORAN-C transmitter was a LORAN-C transmitter at Nanortalik-Kitsissut Islands, Angissoq, Greenland at GRI 7930, 59°59'18"N, 45°10'24" W (). It had a transmission power of 1000 kilowatts. Until July 27, 1964, it used a 1350 ft (411.48 metre) mast radiator, built in 1963. On July 27, 1964, it collapsed from the fatigue failure of an eyebolt head in a compression cone insulator on a structural guy. It was replaced by a 704 ft (214 metre) mast radiator. On December 31, 1994, the transmitter was shut down and the tower dismantled.

Radio Masts And Towers
Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them. In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna. Terminology The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guys. Broadcast engineers in the UK use the same terminology. A mast is a ground-based or rooftop structure that supports antennas at a height where they can satisfactorily send or receive radio waves. Typical masts are of steel lattice or tubular steel construction. Masts themselves play no part in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenland
Greenland ( kl, Kalaallit Nunaat, ; da, Grønland, ) is an island country in North America that is part of the Kingdom of Denmark. It is located between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland is the world's largest island. It is one of three constituent countries that form the Kingdom of Denmark, along with Denmark and the Faroe Islands; the citizens of these countries are all citizens of Denmark and the European Union. Greenland's capital is Nuuk. Though a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and Denmark, the colonial powers) for more than a millennium, beginning in 986.The Fate of Greenland's Vikings , by Dale Mackenzie Brown, ''Archaeological Institute of America'', ...

LORAN-C
Loran-C is a 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 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 the world. Loran-C became one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nanortalik
Nanortalik (), formerly Nennortalik, is a town in Nanortalik Island, Kujalleq municipality, southern Greenland. With 1,185 inhabitants as of 2020, it is the eleventh-largest town in the country. The name ''Nanortalik'' means "Place of Polar Bears" or "Place Where the Polar Bears Go" (from kl, nanoq). It is the southernmost town in Greenland with a population of over 1,000. History Because of its location, this area was one of the first parts of Greenland settled by the Norse and one of the last settled by the Inuit. The town was founded in 1770 as Nennortalik. In 1797, a permanent trading depot was set up in Nanortalik by traders from Julianehåb. Due to poor harbour facilities, the town was moved three kilometers northward in 1830, where it remains today. Of the old town, only some scattered ruins remain. Geography Nanortalik is located on a small island (also named Nanortalik) on the shores of the Labrador Sea, roughly 100 km north of Cape Farewell, the southern tip ...

Kitsissut Islands
Kitsissut (old spelling Kitsigsut) is an island group in the Kujalleq municipality in southern Greenland. Geography Kitsissut is an island chain located about to the west-northwest of Cape Farewell and 15 km to the south-southeast of Cape Egede 5 km from the shore. It is a cluster of numerous small islets and rocks, with a length of less than 30 km and a width of 8 km, divided into two subgroups: Northern Kitsissut ( da, Nordlige Kitsissut) in the northwest and the smaller Southern Kitsissut ( da, Sydlige Kitsissut) in the southeast. Angissoq is the largest island, with a length of 3.7 km and a width of 3 km. It is also the highest island with a peak in its centre on which a beacon A beacon is an intentionally conspicuous device designed to attract attention to a specific location. A common example is the lighthouse, which draws attention to a fixed point that can be used to navigate around obstacles or into port. More mode ... stands.''Prostar Sailing Directions 2005 Gree ...

List Of Masts
The tallest structure in the world is the Burj Khalifa skyscraper at . Listed are guyed masts (such as telecommunication masts), self-supporting towers (such as the CN Tower), skyscrapers (such as the Willis Tower), oil platforms, electricity transmission towers, and bridge support towers. This list is organized by absolute height. See List of tallest buildings and structures, List of tallest freestanding structures and List of tallest buildings and List of tallest towers for additional information about these types of structures. Terminology Terminological and listing criteria follow Council on Tall Buildings and Urban Habitat definitions. Guyed masts are differentiated from towers – the latter not featuring any guy wires or other support structures; and buildings are differentiated from towers – the former having at least 50% of occupiable floor space although both are self-supporting structures. List by height This list includes structures with a minimum height of to k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Towers In Greenland
A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean langua ...
