China Builds World's First GPS Station in Antarctic's Dome Argus

Feb 09, 2009

Chinese scientists built the world's first permanent GPS automatic tracking station in Antarctic's Dome Argus (Dome-A). It will provide geodetic data for surveying and mapping in Dome-A, one of the coldest inland areas in Antarctic.

"The tracking station will provide significant data for Glacial Dynamics research and application research of GPS in troposphere and ionospheric," said Dr. Zhang Shengkai, researcher of the 25th Chinese Antarctic inland expedition team.

Researches can also be carried out on the stable state of inland ice-sheet in Antarctic and space physics through this GPS tracking station, added Zhang.

The station, titled "China Satellite Observatory in Dome-A", will keep working with battery pack providing necessary power supply after expedition teams leave the country's Antarctic research station, Kunlun Station.

The station, formed by a red pole with butterfly-shaped antenna on the top and white FRP radome, stands at the center of the square in front of the Kunlun station's main building.

The Kunlun station, China's third Antarctic research station, also the first on the continent's inland, was erected at Dome Argus (Dome A), the pole's highest icecap at 4,093 meters above the sea level, on Feb. 2 by China's 25th expedition team to the South Pole.
