An ECEF coordinate system is an Earth-based three-dimensional coordinate system with its at the mass-center of the Earth, its aligned with the semi-minor (spin) axis of the Earth defined at some epoch, its in the plane of the equator passing through mean Greenwich meridian, and its in the plane of the equator and creating a coordinate system.

Solution

An ECEF coordinate system is an Earth-based three-dimensional coordinate system with its origin at the mass-center of the Earth, its Z axis aligned with the semi-minor (spin) axis of the Earth defined at some epoch, its X axis in the plane of the equator passing through mean Greenwich meridian, and its Y axis  in the plane of the equator and creating a right-handed coordinate system.
