Researchers develop new ionospheric scintillation model for GNSS

October 12, 2021 - By

Researchers have developed a new mathematical model to more accurately capture how ionospheric scintillation interferes with GNSS signals, reports EOS. The new model uses a Markov chain. The model’s parameters were drawn from data on actual signal disruptions caused by ionospheric scintillation above Hong Kong on March 2, 2014. The researchers compared its predictions with real-world data and found it... read more
