Drones have been all over the media as well as our imaginations. What's real and what's possible for these remarkable flying machines? Todd Humphreys will consider the ways drones can be used in the future versus what is portrayed in the movies. He will also show us how his team was the first to successfully demonstrate that drones could be commandeered by GPS hacking. Presenter’s Biosketch: Todd Humphreys directs the Radionavigation Laboratory at UT-Austin, where advanced radionavigation technology is being developed, and novel ways to exploit and protect radionavigation systems such as GPS are being explored.
