WebApr 11, 2024 · Transforming between Systems ¶. Transforming between Systems. ¶. astropy.coordinates supports a rich system for transforming coordinates from one frame to another. While common astronomy frames are built into Astropy, the transformation infrastructure is dynamic. This means it allows users to define new coordinate frames … WebThe top part goes into how to transform from ECI (GCRF) to ECEF (ITRF); time plays a big role (multiple roles!) in that transformation. Transpose the matrix and you have ECEF to ECI. I agree that the different times make for a bit of a mess, as do the plethora of reference frames. – David Hammen Aug 12, 2014 at 10:37
