High Latitude Scintillation Analysis for Marine and Aviation Applications

F. Ghafoori and S. Skone

Abstract:	In this project research is conducted to quantify ionospheric scintillation impact on GNSS services and operations in the Arctic region. Auroral and polar ionospheric scintillation events are chosen from a Canadian high-latitude GPS database and the observed real scintillation parameters are used to drive GNSS signal simulations. Simulated signals are processed using a software receiver and impact on observation quality is quantified in terms of loss-of-lock probability and tracking errors; number of satellites affected simultaneously is also determined. A generic carrier tracking loop is implemented to determine impact on low-cost single frequency (marine and aviation) receiver performance. Robust receiver settings are recommended to improve receiver tracking capabilities under scintillation conditions.
