UNB researcher, NASA team up on unique GPS research

I like the idea about natural disaster detection, although I wonder about the time lag between the action and the signal affecting the ionosphere. Now that I think about it, though, it's probably not that long.

Richard Langley, a professor at the University of New Brunswick, will be working with the NASA Jet Propulsion Laboratory in California to better understand how the ionosphere affects global positioning systems.

”GPS satellites are much higher than the ionosphere,” Langley said.

”So the signals from the satellites have to come down through the ionosphere to receivers on or near the Earth’s surface. And as they come down through the ionosphere they get a little distorted.”
