Definition

Coordinate system fixed to the rotating Earth, Z-axis parallel to the direction of the North Pole, X-axis defined as the intersection between the fundamental plane and the Greenwich meridian. Also known as ITRF.

Application Value

Earth-Centered Earth-Fixed Frame plays an important role in orbital dynamics and attitude control, serving as a critical tool for analyzing spacecraft motion characteristics. Research on this concept enables optimization of orbit transfer schemes and improvement of control system performance.
