Since made publicly accessible in 2000, GPS has transformed our lives in some surprising ways (and may lead to electrocuting old people who wander too far away). Find out how 33 satellites work together to make sure we’re always being followed.

(No seriously…if you know that last one, let me know.) Enjoy!
