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 کاملPrediction of Total Electron Content over South Africa Using Global Positioning System and Neural Networks
The Global Positioning System (GPS) makes it possible to study the dynamics of the ionosphere by supplementing ionospheric studies carried out using various techniques including ionosondes, incoherent scatter radars and low earth orbit satellites. Total electron content derived from GPS data (GPS TEC) is a key parameter characterising the ionosphere. Its time evolution provides an indication of...
متن کاملEmpirical Modeling of the Total Electron Content of the Ionosphere
With the appearance of such satellite systems as GPS, GLONASS, Galileo, and others, the total electron content TEC measured by means of navigational satellites became a key parameter characterizing a state of the ionized space. In turn, functioning of navigational and telecommunication systems needs models of TEC for an estimation of accuracy of positioning, for the short-term and long-term pre...
متن کاملmodeling and interpolation of ionosphere total electron content using artificial neural network and gps observation
global positioning system (gps) signals provide valuable information about ionosphere physical structure. using these signals, can be derived total electron content (tec) for each line of sight between the receiver and the satellite. for historic and other sparse data sets, the reconstruction of tec images is often performed using multivariate interpolation techniques. recently it has become cl...
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 ...
