    Abstract
  • Based on the data of GPS ionospheric scintillation observed at Guangzhou region in 2014 and 2015, 4820 scintillation spectra and spectral indexes are extracted from 150 typical flicker events. The analyses find that there are mainly two types of scintillation spectra in Guangzhou region, which can be subdivided into five categories. The characteristics and causes of typical scintillation spectrum are analyzed. The study found that the spectral index are from 0.63 to 9.57, and the average spectral index is 3.86. More than 78.5% of the spectral indexes are distributed from 0 to 6. 83.4% of weak scintillation intensity spectral indexes are distributed from 0 to 7, and 89.27% of strong flashing spectral indexes are distributed from 5 to 10. The spectral index increases as the flicker index increasing.
