Okay, so have you ever played hide and seek with your friends? You know how you have to go look for your friends when they hide and you have to do it without cheating and peeking? GPS tracking server is kind of like that, but with machines instead of friends.
You know how you have a phone that tells you where you are when you use maps to get directions to a place? Well, all the big machines like cars and trucks and ships also have a thing called a GPS in them that tells them where they are in the world.
A GPS Tracking Server is like a game master who plays hide and seek with these machines, but the game master never loses track of where the machines are like you might with your friends. The GPS Tracking Server is always keeping track of where each machine is, like where your friends are hiding in the game.
So why is this important? Well, remember how your parents always have to know where you are when you go out? Well, companies that use big machines also need to know where these machines are at all times so they can keep them safe and make sure they are doing their job. The GPS Tracking Server lets the company know where each machine is and if it is doing what it is supposed to be doing.
So, in short, GPS Tracking Server is like a game of hide and seek with machines, but the game master always knows where the machines are so that companies can keep an eye on them and keep them safe.
