Abstract: Recent analysis of GPS data collected by the Federal Aviation Administration’s FAA’s National Satellite Test Bed NSTB indicates that several occurrences of ionospheric scintillation were observed over Alaska on August 6 and 27, 1998. These events coincided with magnetic storms documented by the National Geophysical Data Center. During this period, a specialized L1 GPS receiver designed to monitor scintillation was colocated with the NSTB reference station at Fairbanks, Alaska. This configuration provides data from two different types of receivers: codeless dual-frequency reference measurements survey grade and high-bandwidth scintillation monitoring. The primary goal of this investigation was to determine the effect of scintillation on both single- and dual-frequency users in the auroral zone. The work included estimating the correlation between measured scintillation events and GPS receiver performance. Additionally, the worst-case spatial extent of the scintillation phenomenon was estimated by analyzing the distribution of highly active ionospheric pierce points at the F-layer 350 km altitude.
