Global Positioning System devices around the world were briefly but significantly disrupted late last year by an unexpectedly large blast of radio waves during a solar flare, researchers reported at a conference last week.

But you’d be wrong.
GPS is widely used … in organizing the flow of electricity through power grids and in international financial transactions.
