GPS Scintillation Analysis.

Abstract

Scintillation data recorded by Global Positioning System (GPS) receivers in various locations are examined. This report details our investigation into the validation of the GPS S4 and 60-second phase sigma values for their inclusion into the Air Force Research Laboratory Scintillation Network Decision Aid (SCINDA) as an aid in issuing scintillation warnings and predictions. GOES8 L-band data is compared with GPS S4 and phase sigma levels during moderate scintillation. The construction of and need for site specific masks to reduce the possibility of issuing false scintillation warnings due to persistent anomalous spikes seen in the GPS data, likely due to interference, is also discussed.
