WebThe implementation of the ECI coordinate system assumes that the origin is at the center of the planet, the x -axis is the continuation of the line from the center of the Earth toward the vernal equinox, the z -axis points in the direction of the mean equatorial plane's north pole, positive to the north, and the y -axis completes the right-handed … WebAbstract. This paper assumes the reader is intimately familiar with Special Relativity’s (SRT’s) model and equations. The paper summarizes the empirical data in terms of the two main categories of interpretations of SRT currently taught in 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. great vacuum for short carpet
