Abstract:

The temporal and spatial variations of the ionospheric scintillation event and the influence on communication are studied using GPS measurements at Shenzhen station (Geographic latitude 22.59°N, Geographic Longitude 113.97°E, Geomagnetic Latitude 12.58°N) of Chinese Meridian Project, situated under the northern crest of the equatorial anomaly region, during the period from January 2011 to December 2017. The results show that: GPS scintillation events were largely a nighttime phenomenon, and most of the scintillation events were observed in equinox months; during different solar activity, scintillation events were mainly occurred at the inner edge of the northern crest of equatorial anomaly in China, and scintillation events are more probable to be observed in the west sector of the sky above Shenzhen station; during different solar activity, the weak scintillation events were relatively less accompanied by the TEC depletions and loss of lock on GPS signals, however, most of the strong scintillation events are accompanied by the TEC depletions and loss of lock on GPS signals.

Key words: Ionosphere, Scintillation event, Communication influence
