  • This was an amazingly well done video on GPS! I knew you needed at least 3 satellites for position information but I had the wrong reasons for how they were used - I learned something from watching this video. The inclusion of the fourth one was completely new! And the 3D spherical representations really hammered home the point. Bravo!

No public wish lists :(
