Abstract:Precise ionosphere TEC values are derived from perennial GPS observations during 2000-2006 at Antarctic Zhongshan station, the characteristics of TEC associated with solar activities,geomagnetic environment, and the daily, annual and seasonal TEC variations are studied. Results show that GPSTEC linearly changed with the influence of solar activities and geomagnetic environment while climatologic characteristics of ionosphere are reflected in daily, annual and seasonal TEC variations, as well as polar characteristics of magnetic noon anomaly occurr.
