Abstract :
Signals on satellite to Earth links can be affected by ionospheric scintillation which can lead to a complete loss of lock. This paper presents two scintillation models, the global ionosphere scintillation model (GISM) and hybrid model based on complex phase method and random screen method. Analyzing GPS receiver, this paper describes the effects of ionospheric scintillation on satellite to Earth links using the hybrid model, including phase noise and loss of lock probability.
