Earth centered inertial eci
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, … See more It is convenient to define the orientation of an ECI frame using the Earth's orbit plane and the orientation of the Earth's rotational axis in space. The Earth's orbit plane is called the ecliptic, and it does not coincide with the Earth's … See more • Earth's axial tilt • Geocentric Celestial Reference System • Orbital state vectors See more WebFor Earth-Orbiting satellites, the ECI frame can be considered to be inertial. The position of the satellite relative to the center of the earth is given by the vector r . The position of the …
