Detection and Modeling of Medium-Scale Travelling Ionospheric Disturbances in Iran Region
Ionosphere layer variations are divided into regular and irregular. Regular changes can be considered as daily changes, changes depending on latitude and changes due to solar activity. Travelling Ionospheric Disturbances (TID) is one of the irregular changes of ionosphere which categorized in small, medium and large scales. Medium-scale Travelling Ionospheric Disturbance (MSTID) which are propa...
متن کاملNew approaches in Medium Scale Travelling Ionospheric Disturbances modelling
The Medium Scale Travelling Ionospheric Disturbances (MSTIDs) are the most frequent wave signatures in the ionosphere, with amplitudes up to several TECUs, periods from several hundreds to one-two thousands of seconds, and propagation velocities from 50 to +300 m/s, mainly equator-eastward in winter/fall seasons, and westward in summer/spring seasons (M. Hernandez-Pajares et al., Radio Science,...
متن کاملReal-time Ionospheric Tomography Using Terrestrial GPS Sensors
As a member of the GPS Laboratory his research is focused on wide-area diierential GPS system design, analysis, and application. Mr.Hansen was a member of the technical staa at TASC, Inc. where he worked on DGPS, Loran-C, and Omega radionavigation systems before entering Stanford. He received his BSEE and MSEE from Worcester Polytechnic Institute. ABSTRACT We present a novel technique for estim...
متن کاملImproving the vertical resolution of ionospheric tomography with GPS occultations
We combine GPS/MET data from 29 occultations and IGS ground data collected from 160 stations around the world to perform stochastic tomography of the ionosphere with a 4×20×20 global grid of voxels extending from 200 to 650 km above the mean surface of the Earth. A correlation functional approach that limits the spatial high frequency content of the images is used, and a Kalman filter is applie...
متن کاملIonospheric Calibration of Radar Altimeters Using GPS Tomography
We compare TEC measurements from the NASA Radar Altimeter and DORIS instrument on board TOPEX/POSEIDON with GPS TEC estimates , and evaluate diierent GPS data analysis strategies. We verify that global tomographic GPS analysis using a voxel grid is well suited for ionospheric calibration of altimeters. We show that a 1-day t of 20-second-averaged NRA ionospheric correction data versus GPS tomog...
