Kunlun Station (simplified Chinese: 昆仑站; traditional Chinese: 崑崙站; pinyin: Kūnlún Zhàn) is the southernmost of five Chinese research stations in Antarctica. When it is occupied during the summer, it is the second-southernmost research base in Antarctica , behind only the American Amundsen–Scott South Pole Station at the ...
The Earth-centered, Earth-fixed coordinate system (acronym ECEF), also known as the geocentric coordinate system, is a cartesian spatial reference system that represents locations in the vicinity of the Earth (including its surface, interior, atmosphere, and surrounding outer space) as X, Y, and Z measurements from its center of mass.
Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane and the surface normal at a point on the ellipsoid, whereas geocentric latitude is defined as the angle between the equatorial plane and a radial line connecting the centre of the ellipsoid to a point on the surface (see figure).
Meridians run between the North and South poles. In geography and geodesy, a meridian is the locus connecting points of equal longitude, which is the angle (in degrees or other units) east or west of a given prime meridian (currently, the IERS Reference Meridian). [1] In other words, it is a coordinate line for longitudes, a line of longitude.
The simplest tone remote system uses a two-wire audio circuit to operate a simplex base station. If simultaneous transmit and receive is required, a four-wire or full duplex audio path to the base station is required. Systems using diversity combining (voting) require four-wire circuits.
The base of the Hut Point Peninsula is home to McMurdo Station, Scott Base and Discovery Hut. Scott's Hut is further north on the west coast, at Cape Evans. North of this at Cape Royds is Shackleton's Hut. Finally, the Cape Bird Hut is just south of Cape Bird. [2] McMurdo Station, established in 1955, is the largest station in Antarctica.
Now, Pituffik Space Base, formerly known as Thule Air Base, is one of the most remote U.S. military assignments in the world. Built on permafrost in Greenland's far north, it hosts about 200 troops.
The original Siple I station had a four-person winter over crew and the later Siple II station had an eight-person winter over crew. The Siple II station used a 300 kW Kato square wound generator powered by a Caterpillar D353 engine to power the VLF (Jupiter) transmitter which transmitted to a receiver in Roberval, Canada.
