Discovery About GPS Positioning Regular Daily Ionospheric Scintillation Disturbances

The aim of this study was to find out whether, just like in March 2015, daily regular GPS positioning disturbances caused by ionospheric scin tillations occurred in other months of the solar activity cycle 24. The GPS positioning 90-sec kinematic solutions of selected 46 month covering 11 years were used for search of regular daily scintillation events. The hypothesis on predictable regular daily ionospheric scintillation was tested. Discovered scintillation waves as a result of space weather impact with the siderial day regularity. It leads to conclusion of the radiation origin from the interplanetary media. The enhancement of radiation waves by solar activity is similar as it is for Pc1 waves. The regular daily ionospheric scintillation waves are recorded at any time of the day. In years of low solar activity in 2010 and 2012, regular scintillation waves were not found. It cannot be claimed that the comparison of daily regular ionospheric scintillation cases over time with the mentioned Pc1 wave cases indicates any interrelation.
