Regularized Estimation of Vertical Total Electron Content from Global Positioning System Data
(Amer Geophysical Union, 2003)A novel regularization technique which can combine signals from all Global Positioning System (GPS) satellites for a given instant and a given receiver is developed to estimate the vertical total electron content (VTEC) ... -
A New Algorithm for High-Quality Ionogram Generation and Analysis
(Amer Geophysical Union, 2002)Standard digital ionograms that are generated by fast Fourier transform or autoregressive modeling suffer from high interference levels due to other users of the HF channel which produce artifacts and distortion, hence ... -
Lonolab-Map: An Automatic Spatial Interpolation Algorithm for Total Electron Content
(Tubitak Scientific & Technical Research Council Turkey, 2018)Investigation of the variability of total electron content (TEC) is one of the most important parameters of the observation and monitoring of space weather, which is the main cause of signal disturbance in space-based ... -
Regional Tec Mapping with Random Field Priors and Kriging
(Amer Geophysical Union, 2008)Total Electron Content ( TEC) is an important parameter in monitoring ionospheric variability. In a given region, TEC can be obtained only by interpolation of measurements due to sparsity of the useful data. The lack of a ... -
Spatio-Temporal Interpolation Of Total Electron Content Using A Gps Network
(Amer Geophysical Union, 2013)Constant monitoring and prediction of Space Weather events require investigation of the variability of total electron content (TEC), which is an observable feature of ionosphere using dual-frequency GPS receivers. Due to ... -
