Using GPS to find out exactly where we are is one of the more awesome powers of our mobile devices. It also poses some of the toughest challenges to developers, who must prevent excessive battery drain and deal with insufficient accuracy. In this talk we will learn how to face these challenges by answering questions such as: How does GPS even work? Where the heck did my battery go? Why does it take so long to get a good fix? And why does my phone think I’m in the middle of a lake? If you’ve ever wanted to understand how satellite navigation actually works, this is the talk for you. (It also features cold war intrigue, applied relativity theory, and a picture of a dinosaur. So you know it’s going to be good.)
