Abstract
The application relates to a terminal GNSS and LEO multi-mode multi-frequency ionospheric disturbance monitoring method. The method comprises the following steps: collecting GNSS and LEO satellite full-system and full-frequency point observation data, respectively calculating ionospheric amplitude scintillation indexes, phase indexes and absolute / relative TEC indexes, and outputting high-frequency adjustable original data; integrating four types of indexes and space weather data to construct a training set, extracting feature factors after removing abnormal values through an isolation forest algorithm, inputting the feature factors into an LSTM model to train and optimize hyperparameters; and finally inputting real-time index data into the trained model to realize real-time monitoring of ionospheric disturbance. The method can realize real-time monitoring of ionospheric scintillation.
