GPS - Where in the World Are We?

May 1st, 2010

Episode 225 of 1106 episodes

Where in the world am I? We're looking at the science of the Global Positioning System, or GPS, this week. We find out how satellites can tell you your location, as well as communicate with the bossy little box that tells you which way to drive. We discover the potential for "spoofing" GPS with a false location, and how this might be the future of cyber-terrorism as well as explore the cosmic reference frame that the satellites themselves rely on. In Kitchen Science, we get back to basics and locate ourselves using a map and compass! Plus, the first amphibian genome helps to fill the vertebrate family tree, we meet the colourful fish that shine a light on evolution and find out how a technique developed to study eye disease can help find art forgeries.
