Solar flare signatures of the ionospheric GPS total electron content
6 [1] In this study, ionospheric solar flare effects on the total electron content (TEC) and 7 associated time rate of change (rTEC) derived from ground-based global positioning 8 system (GPS) receivers in the midday region are examined. The occurrence times and 9 locations of 11 solar flares are isolated from the 1–8 Å X-ray radiations of the 10 geosynchronous operational environmental satelli...
متن کاملTotal Ionospheric Electron Content Calibration Using SERIES GPS Satellite Data
This article describes the current status of the Deep Space Network advanced systems research into ionospheric calibration techniques, based on Global Positioning System (GPS) data. A GPS-based calibration system is planned to replace the currently used Faraday rotation method by 1989. The SERIES receiver system used in this research determines the differential group delay of signals transmitte...
متن کاملInvestigation of the relative bottomside/topside contribution to the total electron content estimates
High-resolution vertical electron density true height profiles from Athens Digisonde are used to calculate the electron content up to the peak of the F2 layer (bottomside electron content) and also the topside electron content up to 1000 km, using the Huang-Reinisch method, to investigate the relative behavior of these two parameters during storm events. It was shown that the topside electron c...
متن کاملFeatures of annual and semiannual variations derived from the global ionospheric maps of total electron content
In the present work we use the NASA-JPL global ionospheric maps of total electron content (TEC), firstly to construct TEC maps (TEC vs. magnetic local time MLT, and magnetic latitude MLAT) in the interval from 1999 to 2005. These TEC maps were, in turn, used to estimate the annualto-mean amplitude ratio, A1, and the semiannual-to-mean amplitude ratio, A2, as well as the latitudinal symmetrical ...
متن کاملImproved Modeling of Global Ionospheric Total Electron Content Using Prior Information
The Ionosphere Working Group of the International GNSS Service (IGS) has been a reliable source of global ionospheric maps (GIMs) since 1998. Modeling of the global ionospheric total electron content (TEC) is performed daily by several Ionosphere Associate Analysis Centers (IAACs). Four IAACs (CODE, ESA, CAS and WHU) use the spherical harmonic (SH) expansion as their primary method for modeling...
