Research ArticleOpen accessIn the keywordsLeveling Process of Total Electron Content (TEC) Using Malaysian Global Positioning System (GPS) DataY. Norsuzila, M. Abdullah, M. IsmailThe signals from the satellites of the Navstar Global Positioning System (GPS) travel through the earth's ionosphere on their way to GPS receivers. However, ionospheric delay is one of the main sources of error in GPS. The magnitude of the ionospheric delay is influenced by the Total Electron Content (TEC) along the radio wave path from a GPS satellite to … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,762 accessesView PDF Cite
