class mubody.coordinates.frames.GCRF

Main Earth-centered, equatorial inertial frame.

This is the Geocentric Celestial Reference Frame (GCRF), which is a realization of the Geocentric Celestial Reference System (GCRS). The GCRF is defined using an origin located at the center of the Earth and the same basis vectors as the ICRF [1]. It is very similar to J2000 (EME) inertial system.
