本文介绍了应用ＧＰＳ卫星接收机ＳＮＲ—８Ｃ进行电离层ＴＥＣ观测的数据处理方法，并给出了部分数据处理结果。其中包括应用ＧＰＳ双频信号进行ＴＥＣ计算的原理，应用卫星星历参数计算各时刻电离层质心点的经纬度及卫星仰角和方位角，以及ＴＥＣ的周日变化，逐日变化及一次卫星通过时ＴＥＣ的时空变化结果，讨论了该方法的误差来源及与ＮＮＳＳ方法，法拉第旋转测量ＴＥＣ的比较。应用ＧＰＳ方法测量ＴＥＣ具有很大的优点，具有高精度及多方位的特点。
This paper introduces the data processing method of ionospheric TEC observation using GPS satellite receiver SNR-8C, and gives some data processing results. Including the application of GPS dual-frequency signal TEC calculation principle, the use of satellite ephemeris parameters of each moment of ionospheric centroid latitude and longitude and satellite elevation and azimuth, as well as the TEC sun changes, daily changes and a satellite through the TEC The temporal and spatial variations of the results are discussed. The sources of errors and the comparison with the NNSS method and the Faraday rotation measurement TEC are discussed. The application of GPS method to measure TEC has great advantages, with high precision and multi-directional features.
