Expand description
Cacheable Earth-orientation evaluation for the precise GCRF/ITRF chain.
Provenance: IERS Conventions (2010) TN36 and IAU 2006/2000A are consumed
through the existing precession, nutation, sidereal-time, and polar-motion
routines in crate::astro::frames::transforms. This module does not
reimplement any series; it evaluates the established chain once per epoch and
exposes reusable direction-cosine matrices and state transforms.
Structs§
- Earth
Orientation - A single evaluated Earth-orientation state for one epoch.
- TdbEarth
Orientation Provider - Earth-orientation provider for propagator epochs expressed as TDB seconds since J2000.
Traits§
- Earth
Orientation Provider - Supplies Earth orientation at a propagator integration epoch.
