RESEARCH ON CHARACTERISTICS OF TEC AT ANTARCTIC ZHONGSHAN STATION BASED ON GPS
基于GPS的南极中山站电离层TEC特征研究

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 GPS-TEC 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 characteris...
