Variability of total electron content in the high-altitude ionosphere following solar maximum. Technical report
Northwest Research Associates (NWRA) is recording a database containing measurements of the differential carrier phase (DCP) and the differential group delay (DGD) between the two L-band signals transmitted by satellites of the Global Positioning System (GPS). Data collection is continuing at Shemya, AK, and Hanscom AFB, MA. Software has been, and continues to be, developed to process these data into measurements of trans-ionospheric total electron content (TEC). This database is being analyzed in order to document the variability of TEC and to specify TEC morphology in the region of Shemya, AK. Studies of multipath mitigation and accurate satellite bias determination have been conducted to insure high data quality. Analysis of these and other data developed by NWRA in other high latitude studies in the Shetland Islands, UK, has yielded ionospheric trough boundary signatures.
