Determination of total electron content (TEC) with the use of selected pseudo-random noise code / Amirah Aiyub

Total Electron content (TEC) measurements are made mostly using GPS data because of the good global coverage of the GPS observation network. TEC is an integral of electron density as the signals propagate from the satellites to the Global Positioning System (GPS) receivers and identified as the para...
