WebThe figures defining the frames are reproduced in Figures 2.1 and 2.2. Figure 2.3 shows the location of a ground station, which is tracking a satellite. For 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. WebEarth-Centered, Earth-Fixed# The Earth-centered, Earth-fixed (ECEF) frame is a non-inertial frame, but with the origin still fixed at the center of the Earth. The main difference from the ECI is that the axes in the ECEF rotate at the same rate as the surface of the earth. The ECEF uses lower case, primed letters for the axes and unit vectors.
