OMEGA was the first global-range radio navigation system, operated by the United States in cooperation with six partner nations. It was a hyperbolic navigation system, enabling ships and aircraft to determine their position by receiving very low frequency (VLF) radio signals in the range 10 to 14 kHz, transmitted by a global network of eight fixed terrestrial radio beacons, using a navigation receiver unit. It became operational around 1971 and was shut down in 1997 in favour of the Global Positioning System.
The LORAN-C transmitter Rantum is a transmission facility for LORAN-C on the German island Sylt near the village Rantum at 54°48′30″N8°17′37″E. It was established in the 1960s, initially using a guyed steel framework mast with a triangular cross section, approximately 190 metres tall. In 1996 this mast was replaced by a 193-metre-high mast of the same type but of a better mechanical design. The new mast is, as its forerunner, insulated from ground and has a triangular cross section. The construction, weighing 65 tonnes, is guyed in four levels at 60.52 metres (198.6 ft), 120.87 metres (396.6 ft), 154.95 metres (508.4 ft) and 190 metres (620 ft). The transmitter was shut down on Dec 31, 2015.
The LORAN-C transmitter Jan Mayen was a LORAN-C transmission facility on the island of Jan Mayen at 70°54′51″N8°43′57″W. The LORAN-C transmitter Jan Mayen used as an antenna had a 190-metre tall (625 ft) guyed mast.
Chayka also known as Radiotekhnicheskaya Sistema Dal'ney Navigatsii abbreviated as RSDN is a Russian terrestrial radio navigation system, similar to Loran-C. It operates on similar frequencies around 100 kHz, and uses the same techniques of comparing both the envelope and the signal phase to accurately determine location. The systems differ primarily in details.
Iwo Jima LORAN-C transmitter was a LORAN-C transmitter at Iwo Jima, Japan of Grid 9970 at 24°48′8″N141°19′32″E. The Iwo Jima LORAN-C transmitter had a transmission power of 4 megawatts, which is more than the most powerful broadcasting stations. The Iwo Jima LORAN-C transmitter had a 411.5 meter (1350 ft) tall guyed mast, which was built in 1963. A guy wire insulator eyebolt failed sending the insulator crashing into the tower, knocking it out of plumb. It collapsed in 1964 on repair of the structural damage caused by the insulator. The collapsing tower killed four construction contract workers, three on the tower and one on the ground. The collapse also destroyed the transmitter building.
Angissoq LORAN-C transmitter was a LORAN-C transmitter at Nanortalik-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 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 mast radiator. On December 31, 1994, the transmitter was shut down and the tower dismantled.
Marcus Island LORAN-C transmitter, or Minami Torishima LORAN-C transmitter, is a former LORAN-C transmitter on Minami-Tori-shima in Ogasawara, Tokyo, Japan at. Until 1993 it was part of Grid 9970 and used a transmission power of 4000 kilowatts, which was more than the most powerful broadcasting stations ever used.
LORAN-C transmitter Carolina Beach was the Zulu secondary station of the U.S. Southeast chain of LORAN-C. The transmitter power was 800 kW. The free-standing antenna of 190.5 metres (625 ft) height was situated near Carolina Beach, North Carolina. After the shutdown of Loran-C in the U.S. in 2010, the transmitter and tower radiator were removed.
LORAN-C transmitter Ejde was the Master station of the Ejde LORAN-C Chain. It used a transmission power of 400 kW. Ejde LORAN-C transmitter, situated near Eiði at. Ejde LORAN-C transmitter used as antenna a 190.5 metre tall mast radiator. In 1962 the mast of LORAN-C transmitter Ejde collapsed as a result of a slipping guy rope. The mast has been demolished.
