So this weekend I was doing a bit of research and ended up on a tangent into exactly how GPS works. I get the basics, sure, but wanted to dig into the details a bit more. I didn't have to look any further than the Wikipedia GPS article for an excellent source of information.
While there one of the many resources that caught my eye was the fantastic little "how GPS works" GIF:
It's not often that an animated GIF actually *enhances* a web page, but man, this one is great. The "orbital planes" of the "space vehicles" are clearly displayed in this simple, small, informative graphic (and the movement here is essential, of course). All of the equations in trilateration and such are still a bit over my head, but me likes the pictures ;).
