Okay kiddo, GPS-C stands for GPS Collaboration. It's basically a fancy way that the United States military can share information between different GPS satellites. Think of it like a big group chat between the satellites!
So imagine you and your friends are trying to plan a game of tag. You need to make sure everyone is in the same place at the same time to start the game. GPS-C helps the satellites do the same thing - stay on the same page about where everything is at any given time.
When the satellites all know where everything is, they can work together to give us really precise GPS coordinates. It's like a treasure map that tells you exactly where the treasure is hiding! With GPS-C, we can be even more certain of where we're going and how to get there. Pretty cool, huh?
