New blog post: Can GPS navigate us to covert underground nuclear test sites?

An op-ed recently published in the Bulletin of the Atomic Scientists suggests that there might be a new way to detect underground nuclear test explosions. The authors, a group of scientists from Ohio State University, have been working on turning a troublesome vulnerability of a common system into something useful. Their findings suggest that data from Global Positioning Systems (GPS), commonly used in navigation, could be used to augment existing detection techniques by detecting airborne shockwaves created by covert test explosions. The location of such explosions can then be narrowed down by comparing data on these shockwaves collected from nearby GPS receivers. This seems like a fascinating potential use of existing technology. However, there is an important issue which could prevent it from becoming a reality.
