Scintillations effects on satellite to Earth links for telecommunication and navigation purposes
Radio wave scintillations are rapid fluctuations in both amplitude and phase of signals propagating through the atmosphere. GPS signals can be affected by these disturbances which can lead to a complete loss of lock when the...
