We've been hearing this week about GPS, the technology behind the mapping software on our phones. It is now involved in everything from the electrical grid to how we grow crops. In fact, according to author Greg Milner, the US has 16 critical infrastructure sectors, including energy, dams, and agriculture. And all but three of them use GPS for some essential function.
Here & Now's Jeremy Hobson talks with Greg Milner about some of the security concerns that have come up involving GPS.
This is the second of a two-part conversation. Listen to the first half of our discussion, which aired yesterday.
