The Prediction Model of Diurnal Ionosphere TEC Based on TWSTFT

This paper estimated the local model to predict ionosphere TEC on a scale of day. Ionosphere TEC were obtained from the two-way satellite time and frequency transfer (TWSTFT), based on these data a sine function was fitted by iteration to get the prediction model of diurnal ionosphere TEC. This model simply and directly reflected the characteristic of the diurnal ionosphere behavior, and was consistent with the corresponding Ionosphere TEC obtained from TWSTFT.
