Why does my phone gps know which way I’m facing when driving, but when walking it always thinks I’m walking backwards?
In: Technology
GPS has no idea which way you’re facing. Your phone does, though, because it has a compass built into it. That compass tells the app you’re using which way your facing, and the GPS tells the app where you are. The app puts them together to give you a whole picture of where you are and where you’re headed.
