A Look at High-Latitude and Equatorial Ionospheric Disturbances of GPS Signals
In an effort to help improve the monitoring, mapping, and modeling of scintillations, a team of researchers led by Prof. Jade Morton is monitoring high-latitude and equatorial scintillations and they discuss some of their preliminary results in this month’s column.
Performance of the Galileo Single-Frequency Ionospheric Correction During In-Orbit ValidationIn this month’s column, a team of researchers from ESTEC describe the European way for modeling the ionosphere for single-frequency users and compare its performance to the current GPS approach.
Greater Fidelity Using a 3D Approach
In this month’s column we look at the performance of a 3D approach to modeling the ionosphere, including times when the ionosphere is particularly interesting (read disturbed).
After a two-week delay, a rocket carrying a GPS instrument designed by University of New Brunswick scientists was […]
Update: Elon Musk, SpaceX’s CEO and chief designer, has posted an update on the status of the upcoming […]
Monitoring the Ionosphere with Integer-Leveled GPS MeasurementsI am joined by two of my graduate students, who report on an advance in the signal processing procedure for better monitoring of the ionosphere, potentially allowing scientists to get an even better handle on what’s going on above our heads.
The explosion of an underground nuclear device by North Korea this week disturbed the Earth’s ionosphere. The blast […]
