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 ... -
Estimation Of Single Station Interfrequency Receiver Bias Using Gps-Tec
(Amer Geophysical Union, 2008)Dual-frequency Global Positioning System (GPS) receivers present a plausible and cost-effective way of computing Total Electron Content (TEC). For accurate estimates of TEC, frequency-dependent satellite and receiver ... -
Investigation of Total Electron Content Variability Due to Seismic and Geomagnetic Disturbances in the Lonosphere
(Amer Geophysical Union, 2010)Variations in solar, geomagnetic, and seismic activity can cause deviations in the ionospheric plasma that can be detected as disturbances in both natural and man-made signals. Total electron content (TEC) is an efficient ... -
Mode Separation And Direction Of Arrival Estimation In Hf Links
(Amer Geophysical Union, 2003)[1] Estimation of arrival angles and incoming signals is a challenging problem for HF channels where the signals are correlated and the separation between the signals can be as low as a couple of degrees. In this paper, a ... -
Online User-Friendly Slant Total Electron Content Computation From Iri-Plas: Iri-Plas-Stec
(Amer Geophysical Union, 2014)Slant total electron content (STEC), the total number of free electrons on a ray path, is an important space weather observable. STEC is the main input for computerized ionospheric tomography (CIT). STEC can be estimated ... -
Regional Model-Based Computerized Ionospheric Tomography Using Gps Measurements: Ionolab-Cit
(Amer Geophysical Union, 2015)Three-dimensional imaging of the electron density distribution in the ionosphere is a crucial task for investigating the ionospheric effects. Dual-frequency Global Positioning System (GPS) satellite signals can be used to ... -
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 ... -
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) ... -
Regularized Estimation of Vertical Total Electron Content From Gps Data For A Desired Time Period
(Amer Geophysical Union, 2004)In this paper a new algorithm for short-term regularized estimation of vertical total electron content (VTEC) from Global Positioning System (GPS) data is developed. The regularization technique can combine signals, from ... -
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 ... -
Total Electron Content Estimation With Reg-Est
(Amer Geophysical Union, 2007)Total Electron Content ( TEC) constitutes one of the key elements for observing the variable structure of the ionosphere. GPS provides a cost- effective alternative in TEC estimation through earth- based receivers. In this ...
