Geomagnetic storm effects on GPS based navigation
The energetic events on the sun, solar wind and subsequent effects on the Earth’s geomagnetic field and upper atmosphere (ionosphere) comprise space weather. Modern navigation systems that use radio-wave signals, reflecting from or propagating through the ionosphere as a means of determining range or distance, are vulnerable to a variety of effects that can degrade the performance of the naviga...
متن کاملEffects 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 کاملIonospheric total electron content (TEC) studies with GPS in the equatorial region
This paper essentially deals with the effects of equatorial ionization anomaly gradient on space-based navigation systems like GPS. The equatorial region of the ionosphere, which extends about ±30dip about the magnetic equator, is characterized by a steep latitudinal gradient, not only in the maximum ionization but also in the total electron content (TEC), through a major part of the day. This ...

15 صفحه اولSolar 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...
