WebFeb 1, 2016 · A simplified equation for transforming a velocity vector v → between the ITRS and GCRS (that is sufficient for most applications) is Vallado (2013) (5) v → GCRS = C R W v → ITRS + ω → ⊕ × W r → ITRS, where ω → ⊕ = 0 0 ω ⊕ T is the rotation vector of the Earth in the Terrestrial Intermediate Coordinate System (TIRS) and the ... WebNov 5, 2024 · @StuartLittlefair - it does seem the AltAz.location always is used as in locitrs = altaz_frame.location.get_itrs(obstime), i.e., ITRS, but the others assume GCRS. It might actually be easiest if the location is simply a frame instance of any kind, and gets transformed as needed.

WebJan 1, 2012 · The CIP acts as intermediate pole in the transformation between the GCRS and the ITRS. Its motion in the GCRS is described by the motion of the ITRS pole with periods larger than 2 days. The position is fixed by the IAU 2000A model for precession–nutation and the frame bias. Frequencies in the GCRS and ITRS are …
