WebThe ( r −θ − i ) coordinate system (Earth Centered Chief Satellite Orbital Plane coordinate system ) is used in describing the J 2 disturbance in the local ( x - y - z ) coordinate system. Earth-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.
