Hierarchical coordinate frames - crystal clear transforms
Scalar Magnitudes are invariant quantities that conserve their value and form under transformations of translation and rotation, or changes between coordinate systems (Cartesian, polar, spherical, etc.)
Relational Magnitudes are invariant vectorial quantities that conserve their value and form under transformations of translation and rotation.
International Terrestrial Reference Frame (ITRF) Matlab Toolbox
A Fortran library to interpolate the MOON_PA reference frame without using SPICE.
Short code for converting TEME reference frame obtained from SGP4 propagation into ITRF and J2000 reference frames.
