ANARESAT
ANARESAT or ''Australian National Antarctic Research Expeditions Satellite'' is a communication solution using Intelsat Geostationary communication satellites to allow Australian Antarctic Division sites to communicate. The installation includes a 7.3 m dish antenna, and a large dark dome to protect the satellite from the harsh weather conditions. It was installed at: * Davis Station in March 1987, * Mawson Station in January 1988, * Casey Station in March 1988, and * Macquarie Island Station The Macquarie Island Station is a permanent Australian subantarctic research base on Macquarie Island, commonly called Macca, situated in the Southern Ocean and located approximately halfway between mainland Australia and Antarctica, managed by ... in December 1988.

Davis Station
The Davis Station, commonly called Davis, is one of three permanent bases and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Davis is situated on the coast of Cooperation Sea in Princess Elizabeth Land, Ingrid Christensen Coast in the Australian Antarctic Territory, a territory claimed by Australia. Davis lies in the Antarctic oasis, a remarkable ice free area known as the Vestfold Hills. Davis was named in honour of Captain John King Davis. Davis was listed on the Register of the National Estate on 26 October 1999 and has been included on the Commonwealth Heritage List as an indicative place, due to the condition of buildings and structures that varies from no longer exists/demolished due to poor condition, through to very good condition. Purpose Davis is a base for scientific research programs including the study of viruses and bacteria using molecular genetic techniques in glacial lakes, the impact of environmental change and pollution ...

Mawson Station
The Mawson Station, commonly called Mawson, is one of three permanent bases and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Mawson lies in Holme Bay in Mac. Robertson Land, East Antarctica in the Australian Antarctic Territory, a territory claimed by Australia. Established in 1954, Mawson is Australia's oldest Antarctic station and the oldest continuously inhabited Antarctic station south of the Antarctic Circle. Mawson was named in honour of the Australian Antarctic explorer Sir Douglas Mawson. Mawson was listed on the Register of the National Estate in 2001 and listed on the Commonwealth Heritage List on 22 June 2004, reflecting the post-World War Two revival of Australia's scientific research and territorial interests in Antarctica. Purpose Mawson Station is a base for scientific research programs including an underground cosmic ray detector, various long-term meteorological aeronomy and geomagnetic studies, as well as ongoing cons ...

Casey Station
Casey Station, commonly called Casey, is one of three permanent stations and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Casey lies on the northern side of the Bailey Peninsula (Antarctica), Bailey Peninsula overlooking Vincennes Bay on the Budd Coast of Wilkes Land in the Australian Antarctic Territory, a States and territories of Australia, territory claimed by Australia. Casey is due south of Perth, Western Australia, Perth, Western Australia. Casey was named in honour of Richard Casey, Baron Casey, Richard, Baron Casey. History Casey is close to the now-abandoned Wilkes Station, established by the United States of America to support science and exploration of Antarctica during the International Geophysical Year (IGY) in 1957–1958. Australia took Wilkes over after the IGY, but the American buildings were already unusable due to the build-up of ice around them. Australia built the first Casey Base, originally as "Repstat", referri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macquarie Island Station
The Macquarie Island Station is a permanent Australian subantarctic research base on Macquarie Island, commonly called Macca, situated in the Southern Ocean and located approximately halfway between mainland Australia and Antarctica, managed by the Australian Antarctic Division (AAD). The station lies at the base of Wireless Hill, between two bays on the isthmus at the northern end of the island. The island and its surrounding waters are administered as a nature reserve by the Tasmanian Government Parks and Wildlife Service. In 1997 the island was inscribed on the UNESCO World Heritage List as a site of major geoconservation significance, being the only place on earth where rocks from the earth's mantle are actively exposed above sea-level. Purpose The research station is operated by the Australian Antarctic Division. Scientific research on the island is focused around biology, geosciences, meteorology, and human impact on the environment. Macquarie island birds breed on the i ...

Intelsat
Intelsat S.A. (formerly INTEL-SAT, INTELSAT, Intelsat) is a multinational satellite services provider with corporate headquarters in Luxembourg and administrative headquarters in Tysons Corner, Virginia, United States. Originally formed as International Telecommunications Satellite Organization (''ITSO'', or INTELSAT), from 1964 to 2001, it was an intergovernmental consortium owning and managing a constellation of communications satellites providing international telecommunications and broadcast services. As of June 2022, Intelsat operated a fleet of 52 communications satellites which was then one of the world's largest fleets. In 2020, the company announced plans to procure, build and launch seven C-band satellites over the next several years. These C-band satellites will contribute to the acceleration of America's 5G buildout. In early 2022, the company announced contracts for four GEO software defined satellites (SDS), two in partnership with Airbus and two in partnership ...

Geostationary Communication Satellite
A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period. Such a satellite returns to the same position in the sky after each sidereal day, and over the course of a day traces out a path in the sky that is typically some form of analemma. A special case of geosynchronous satellite is the geostationary satellite, which has a geostationary orbit – a circular geosynchronous orbit directly above the Earth's equator. Another type of geosynchronous orbit used by satellites is the Tundra elliptical orbit. Geostationary satellites have the unique property of remaining permanently fixed in exactly the same position in the sky as viewed from any fixed location on Earth, meaning that ground-based antennas do not need to track them but can remain fixed in one direction. Such satellites are often used for communication purposes; a geosynchronous network is a communication network based on communication with or throu ...

Australian Antarctic Division
The Australian Antarctic Division (AAD) is a division of the Department of Climate Change, Energy, the Environment and Water. The Division undertakes science programs and research projects to contribute to an understanding of Antarctica and the Southern Ocean. It conducts and supports collaborative research programs with other Australian and international organisations, such as the Bureau of Meteorology and Geoscience Australia, as well as administering and maintaining a presence in Australian Antarctic and sub-Antarctic territories. Their website includes articles on the Antarctic wildlife, threats, guidelines and they have blogs written by Australians at the three Australian bases in Antarctica: Mawson, Davis and Casey. Charter Under its charter the Australian Antarctic Division: * Administers the Australian Antarctic Territory and the Territory of Heard Island and McDonald Islands * Conducts research in high priority areas of Antarctic science * Coordinates and manages ...
