Ionosphere Scintillation Signal Parameters Modeling Based on Triple Frequency Software GNSS Receiver Measurements

Abstract:	Ionosphere scintillations can cause significant amplitude and/or phase fluctuations of GNSS signals. This paper presents studies of scintillation effects on the new GPS L2C, and L5 signals based on data collected using a GNSS receiver array at the HAARP facility in Alaska. The receivers used in this study includes a custom narrow-band front end that collects GPS L1 and L2 IF samples and a reconfigurable USRP2-based RF front end to collect wideband GPS L5 signals. Ionosphere scintillation are expected to have stronger impacts on the new GPS L2C and L5 signals due to their lower carrier frequencies compared to L1. This paper presents quantitative relationships among GPS L1, L2, and L5 carrier tracking results based on eight natural scintillation events during 2011. The results confirm that scintillation has a stronger impact on GPS L2 and L5 signals than on the L1 signal and that carrier phase and amplitude scintillations on different frequency channels are highly correlated.
