COSMIC-2 RFI Prediction Model Based on CNN-BiLSTM-Attention for Interference Detection and Location. [PDF]
Sensors (Basel)As the application of the Global Navigation Satellite System (GNSS) continues to expand, its stability and safety issues are receiving more and more attention, especially the interference problem. Interference reduces the signal reception quality of ground terminals and may even lead to the paralysis of GNSS function in severe cases.
