GPS System Can Detect Secret Nuclear Tests -- Field TechnologiesThis week researchers at Ohio State University revealed they have a new tool for detecting illegal nuclear explosions: the Earth’s global positioning system (GPS). The discovery was announced this week at a Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) meeting.
Researchers have discovered that nuclear tests leave a mark on the part of the upper atmosphere known as the ionosphere. After a nuclear explosion, there is a change in ionospheric electron density, as a bubble of disturbed particles spread out from the test site and across the planet. As the GPS signal passes through the edge of the bubble, the change in electron density disturbs the signal in a noticeable way.
