Real-Time TEC Determination for Ionospheric Modeling in WADGPS

Jose Fraile-Ordonez

Abstract:	In this paper, an algorithm for the real-time computati- on of Ionospheric Total Electron Content (TEC) will be presented. The computation is based on a sequential least-squares algorithm applied to dual frequency GPS pseudorange and carrier phase measurements. It will be shown that this combination enables a strong reduction of noise on the TEC determination as compared to TEC values computed from simple frequency differenced pseudoranges. Thanks to its real-time processing capability, this al- gorithm is mainly expected to be implemented in Wide Area Differential GPS Reference Stations or in Io- nosphere Monitoring Stations.
