Ionospheric prediction of low latitude airport based on Beidou Navigation System

Method of Ionospheric total electron content (TEC) forecasting at low latitude areas can help the aircraft which using Global Navigation Satellite System (GNSS) to provide rapid warning of ionospheric anomalies. In this paper, we are going to build a model for TEC forecasting. First, we collect the TEC data at low latitude airport. Then we propose a GBDT-based LightGBM model. The prediction results show that this model can well predict the trend of ionospheric VTECU numerical fluctuation, indicating that it is feasible to early warning ionospheric anomalies.
