Jorn Hoel
The Jindalee Operational Radar Network (JORN) is an over-the-horizon radar (OHR) network that can monitor air and sea movements across . It has a normal operating range of to . It is used in the defence of Australia, and can also monitor maritime operations, wave heights and wind directions. JORN's main ground stations comprise a control centre, known as the JORN Coordination Centre (JCC), at RAAF Base Edinburgh in South Australia and three transmission stations: Radar 1 near Longreach, Queensland, Radar 2 near Laverton, Western Australia and Radar 3 near Alice Springs, Northern Territory. History The roots of the JORN can be traced back to post World War II experiments in the United States and a series of Australian experiments at DSTO Edinburgh, South Australia beginning in the early 1950s. In 1969, The Technical Cooperation Program membership and papers by John Strath prompted development of a core "Over the Horizon" radar project. From July 1970 a study was undertaken ...

Leonora, Western Australia
Leonora is a town in the Goldfields-Esperance region of Western Australia, located northeast of the state capital, Perth, and north of the city of Kalgoorlie. History The first European explorer to visit the area was John Forrest in 1869. On 21 June 1869 Forrest's party made camp near a conspicuous hill, which Forrest named Mount Leonora, after his six-year-old niece Frances (Fanny) Leonora Hardey. In 1895, gold was discovered in the area by prospector Edward "Doodah" Sullivan at the Johannesburg lease just north of the current townsite. In the following two years a number of rich finds resulted in rapid development of the area. The Sons of Gwalia gold mine brought Leonora to the attention of the world. By 1897 a residential and business area had been established, and the town was gazetted as Leonora. Leonora had a single track passenger tramway linking the town and nearby Gwalia, from 1901 to 1921. Initially steam driven, the service was electric from November 1908, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ionosonde
An ionosonde, or chirpsounder, is a special radar for the examination of the ionosphere. The basic ionosonde technology was invented in 1925 by Gregory Breit and Merle A. Tuve and further developed in the late 1920s by a number of prominent physicists, including Edward Victor Appleton. The term ''ionosphere'' and hence, the etymology of its derivatives, was proposed by Robert Watson-Watt. Components An ionosonde consists of: * A high frequency (HF) radio transmitter, automatically tunable over a wide range. Typically the frequency coverage is 0.5–23 MHz or 1–40 MHz, though normally sweeps are confined to approximately 1.6–12 MHz. * A tracking HF receiver which can automatically track the frequency of the transmitter. * An antenna with a suitable radiation pattern, which transmits well vertically upwards and is efficient over the whole frequency range used. * Digital control and data analysis circuits. The transmitter sweeps all or part of the HF frequency ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transponders
In telecommunications, a transponder is a device that, upon receiving a signal, emits a different signal in response. The term is a blend of ''transmitter'' and ''responder''. In air navigation or radio frequency identification, a flight transponder is an automated transceiver in an aircraft that emits a coded identifying signal in response to an interrogating received signal. In a communications satellite, a satellite transponder receives signals over a range of uplink frequencies, usually from a satellite ground station; the transponder amplifies them, and re-transmits them on a different set of downlink frequencies to receivers on Earth, often without changing the content of the received signal or signals. Satellite/broadcast communications A communications satellite’s channels are called transponders because each is a separate transceiver or repeater. With digital video data compression and multiplexing, several video and audio channels may travel through a single trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aviation Week & Space Technology
''Aviation Week & Space Technology'', often abbreviated ''Aviation Week'' or ''AW&ST'', is the flagship magazine of the Aviation Week Network. The weekly magazine is available in print and online, reporting on the aerospace, defense and aviation industries, with a core focus on aerospace technology. It has a reputation for its contacts inside the United States military and industry organizations. ''Aviation Week'' was a favorite conduit for defense-related companies and labs to leak information to the public as part of their policy by press release efforts. This led to it being informally referred to "Aviation Leak and Space Mythology". History The magazine was first published in August 1916. Early editors Ladislas d'Orsy and Donald W. McIlhiney (1921 to 25) were Quiet Birdmen. Publisher (1927 to 29) Earl D. Osborn was also a Quiet Birdman. With the coming of the Space Age, the current title was adopted in 1960. Other titles the magazine has held include ''Aviation & Aircraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tenix
Tenix is a privately owned Australian company involved in a range of infrastructure maintenance and engineering products and services to the utility, transport, mining and industrial sectors in Australia, New Zealand, the Pacific Islands, and the United States. The antecedent company Transfield was established in 1956 by Carlo Salteri and Franco Belgiorno-Nettis. The company focused on engineering and infrastructure construction, and expanded into the naval shipbuilding industry in the 1980s (initially under the name AMECON, then Transfield Defence Systems). A 1995 dispute between the company's managing directors (the eldest sons of the two founders) led to Transfied being split in two; the Belgiorno-Nettis family kept the Transfield name and the construction side of the business, while the Salteri family retained the infrastructure, defence, and technology elements, which were relaunched in 1997 as several companies under the Tenix name. Tenix Defence grew to become one of Aus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
