Technical Note on POlarimetric Phase Interferometry (POPI)
Estel Cardellach, Serni Ribó, Antonio Rius
The Global Navigation Satellite Systems (GNSS), such as the American Global Positioning System (GPS), the Russian GLONASS or the imminent European Galileo, can be used as sources o…
Analysis of Water Vapor spatio-temporal structure over the Madrid Area using GPS data
Giulio Ruffini, Antonio Rius, Lidia Cucurull +1
We have analyzed Zenith Wet Delay (ZWD) time series from an experiment over the Madrid (Spain) area obtained from 5 GPS receivers using two different techniques. In the first case…
GIST: A tool for Global Ionospheric Tomography using GPS ground and LEO d ata and sources of opportunity with applications in instrument calibration
A. Flores, G. Ruffini, A. Rius +1
Ionospheric tomography using GPS data has been reported in the literature and even the application to radar altimeter calibration was succesfully carried out in a recent work. We h…
4D Tropospheric Tomography using GPS Estimated Slant Delays
A. Flores, G. Ruffini, A. Rius
Tomographic techniques are successfully applied to obtain 4D images of the tropospheric refractivity in a local dense network. In the lower atmosphere both the small height and tim…
A PIM-aided Kalman Filter for GPS Tomography of the Ionospheric Electron Content
Giulio Ruffini, Lidia Cucurull, Alex Flores +1
We develop the formalism for a PIM-based functional for stochastic tomography with a Kalman filter, in which the inversion problem associated with four-dimensional ionospheric stoc…
