Vec6 lupnt::EmeToGcrf(const Vec6 &rv_eme)

Converts a state vector from EME2000 (J2000 mean equator/equinox) to GCRF by applying the inverse of the constant IAU frame-bias rotation.

Used by ConvertFrame when converting an EME/ECI-frame state into GCRF (the hub frame from which all other Earth/Moon frame conversions are reached).

Note

Parameters:

rv_eme – Position+velocity in EME2000 (ECI) [m, m/s]

Returns:

Position+velocity in GCRF [m, m/s]
