Influence of Ionospheric Scintillation on GPS Tracking Loop
Abstract：The ionospheric scintillation which affects the positioning performance of the satellite navigation system is important factor. The paper introduces the S4 index which can give the strength of the amplitude fading. The paper establishes the model of the fluctuation of the c/no by the relationship between Ionospheric scintillation and the c/no. It gets the probability of the GPS receiver tracking loops losing lock in the influence of Ionospheric scintillation. Analysis results show that with the lower c/no and ionospheric scintillation intensity increase the probability of the receiver tracking loops losing lock is greater.
