摘　　要：随着太空探测技术的进步,对TEC(Total Electron Content,简称TEC)探测精度要求越来越高.本文利用COSMOS 2414卫星数据资料获得观测TEC,在电离层NeQuick模型下,得到电离层电子密度,并使用卡尔曼滤波算法反演电子密度,最后结合电离层测高仪数据对实验结果进行判定.结果发现利用卡尔曼滤波反演信标资料算法,可以获得可靠的二维电子密度场.As an important part of solar-terrestrial space environment, the ionosphere has a great effect on radio communications, satellite navigation and positioning, and the human space activities. Total electron content （TEC） is an important content of the ionosphere detection, therefore, it is of great significance to improve the TEC precision. This paper uses satellite beacon technology to get TEC and Kalman Filter algorithm to retrieve ionospheric electron density;the experiment result is evaluated with the ionosphere altimeter data. It is found that using Kalman Filtering algorithm for beacon data inversion, reliable 2-D density field can be obtained.
