Experiment aboard space station studies 'space weather'

The weather here on Earth has been a little strange this winter – 60-degree days, followed by blinding snow, only to be followed by 50s and rain – but for Steven Powell, the weather he's interested in can't be felt by ...

Easy prey for hackers—navigation systems

When it comes to route planning, drivers have almost blind faith in GPS; the technology plays a crucial role in identifying location and time in the industry as well as in other areas. If hackers attack the system, they can ...

Sharper GPS needs even more accurate atomic clocks

The GPS network might just be Earth's greatest piece of infrastructure. It's effectively a collection of clocks in space that serve up time information 24/7 free of charge to anyone on the planet who cares to listen.

Iceland rises as its glaciers melt from climate change

The Earth's crust under Iceland is rebounding as global warming melts the island's great ice caps, a University of Arizona-led team reports in an upcoming issue of Geophysical Research Letters.

Cruising high seas, engineers detect fake GPS signals

Cruising the Mediterranean aboard a superyacht, a Cornell professor and grad student took their Global Positioning System (GPS) research to the high seas. For four days in late June, they tested the newest version of their ...

NASA uses GPS to find Sierra water weight

(Phys.org) —For the first time, NASA scientists have used GPS to find the total weight of winter snowpack and soil moisture in California's Sierra Nevada. The new results complement other satellite measurements and could ...

New airborne GPS technology for weather conditions takes flight

GPS technology has broadly advanced science and society's ability to pinpoint precise information, from driving directions to tracking ground motions during earthquakes. A new technique led by a researcher at Scripps Institution ...
