WebThe axes OX p and OY p lie in the equatorial plane, and the axis OZ p is directed along the Earth’s rotation axis toward the Earth’s North Pole. The axis OX p is directed to the vernal equinox. This frame is known as the Earth-centered-inertial (ECI) frame (Schaub and Junkins, 2014). The Earth itself rotates relative to this frame. WebMar 31, 2024 · There are a number of different Earth Centered Inertial frames, and the answer depends on which one you have your coordinates in. The most common is so-called J2000; which is defined w.r.t to the orientation of the Earth on Jan 1st 2000.
