Earth Orientation Parameters

Earth Orientation Parameters (EOP) are a collection of measurements that describe how the Earth's rotation and position in space change over time. They include factors like the Earth's wobble, tilt, and slight shifts in its spin axis, as well as the length of a day. These parameters are crucial for accurate navigation, satellite communication, and astronomy because they help determine the precise location and orientation of the Earth at any given moment. Essentially, EOP track the subtle movements of Earth, ensuring that our global position and timing systems stay precise.
