The angle that it makes with the x E C I axis is known as the Earth Rotation Angle (ERA) or Greenwich Sidereal Angle. To convert between ECI and ECEF frames, we must first gain the ERA denoted as γ ∈ [ 0, 2 π].

The Y axis is then set inbook x2 specsEarth-centered inertial (ECI) coordinate frames have their origins at the center of mass of Earth and are fixed with respect to the stars. "I" in "ECI" stands for inertial (i.e. "not accelerating"), in contrast to the "Earth-centered - Earth-fixed" (ECEF) frames, which remains fixed with respect to Earth's surface in its rotation, and then rotates with respect to stars. incident in seahamWebMeaning of earth centered.
