Last week, I showed you a method of how to find the fastest path from A to B: Finding the Shortest Path with Dijkstraâ€™s Algorithm. To make use of that, we need a method to determine our position at any point in time.

For that matter, many devices use the so-called *Global Positioning System (GPS)*. If you want to understand how it works and do some simple calculations in R, read on!
