ECEF
ECEF stands for Earth-Centered, Earth-Fixed, which is a special kind of coordinate system used to describe locations on Earth. Imagine a giant globe sitting in the middle of your room. ECEF uses this globe as a reference point and considers it to be fixed or not moving. It also considers the center of the Earth as the center of the globe.
Now let's pretend you are playing a game of "pin the tail on the donkey" with your friends. Each friend puts a sticker on the globe where they think they live. The globe will have many stickers and each one represents a different location.
Instead of using stickers, ECEF uses three numbers (like x, y, and z) to describe the location of each point. These numbers are called coordinates and are a bit like an address for each point on the globe. They are measured in meters and tell you how far away each point is from the center of the Earth (which remember, is the center of the globe).
So when someone uses ECEF, they give these three numbers to describe a location on Earth. This allows people to talk about exact positions, like where a satellite is in space or where an airplane is flying. It's like giving someone your home address so they know exactly where to find you!
