摘要
电离层总电子含量(TEC)的精确预报对提高GNSS导航精度,保障无线电空间远程通讯具有重要作用。分析了IGS发布的电离层格网点总电子含量(TEC)的时间序列特点,基于时间序列分析理论,以AR模型对格网点TEC随机时间序列平稳化后建模和预报。实例分析表明,研究的预报技术和方法是可行的。
Accurately forecasting the ionospheric total electron content plays an important role in improving GNSS navigation and protecting remote radio communication. The characteristic of the TEC time series values for the ionosphere grid point observed hy International on time series analysis, AR models are built for the used for forecasting ionospheric TEC. The nique is feasible by illustration. GPS Servicer is analyzed in this paper. Based stationary time series values at the ionospheric grid and preliminary result shows the proposed methodology and tech nique is feasible by illustration.
