Retrurn the Earth Rotation Angle (In Degrees) as measured by GMST (Greenwich Mean Sidereal Time)
It refers to the angle of Earth's rotation relative to the fixed stars, specifically the hour angle of the mean vernal equinox as observed from the Greenwich meridian. It represents how far Earth has rotated since the mean equinox crossed the Greenwich meridian; It is essentially a way to measure Earth's rotation in angular terms based on a celestial reference point.
