Effects of St Patrick’s Day Intervals Geomagnetic Storms on the Accuracy of GNSS Positioning and Total Electron Content over Nigeria
Total electron content (TEC) and GNSS positioning error over two Nigeria GNSS stations (CLBR: Latitude; 4.9503°E, Longitude; 8.3514°N, FUTY: Latitude; 9.3497°E, Longitude; 12.4978°N) were studied during the geomagnetic storms of March 17, 2015 minimum Dst (Disturbed storm time) -223nT and that of March 17, 2013 minimum Dst of -132nT (the St. Patrick’s...
متن کاملanalysis and prediction of gnss estimated total electron contents
the least squares harmonic estimation is applied to the hourly time-series of total electron contents (tec) derived from ionospheric models using seven years of gps observations processed by bernese software. the frequencies of dominant spectral components in the spectrum are estimated. we observe significant periodic patterns with periods of 24 h and its fractions 24h/n, n=2,…,11, which are th...
متن کاملEvolutionary Prediction of Total Electron Content over Cyprus
Total Electron Content (TEC) is an ionospheric characteristic used to derive the signal delay imposed by the ionosphere on trans-ionospheric links and subsequently overwhelm its negative impact in accurate position determination. In this paper, an Evolutionary Algorithm (EA), and particularly a Genetic Programming (GP) based model is designed. The proposed model is based on the main factors tha...
متن کاملSolar 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...
