Variability of Total Electron Content in the High-Latitude Ionosphere FollowingSolar Maximum

摘要

A data archive of Total Electron Content CIEC data was developed throughoperation and maintenance of GPS satellite receiver equipment at Shemya, AK; Hanscom AFB, MA; Thule AB, Greenland; Tucuman, Argentina; and Agua Verde, Chile. Scintillation data can be extracted ftom much of this database. The Shemya, AK, data provide a valuable source for characterizing TEC morphology and variability with look direction at this site. The Shemya data were also used in an initial assessment of the seasonal and directional specification accuracy of the Bent ionospheric model, specific to this site. Analysis of an existing NWRA database has produced ionospheric trough boundary signatures in the sub auroral European sector. These signatures will support studies aimed at real time detection of the trough boundary. Innovative software techniques were developed to improve data quality in the areas of multipath rnitigation (the Multipath Template Technique) and the automated calibration of an installed receiver system for the combination of all system components' contributions to pseudorange error (SCORE:: Self-Calibration Of pseudoRange Errors).
