WebJun 3, 2024 · First, we all know that TEME is in the class of ECI (non-rotating) reference systems, with the prime direction (X) pointing along the Vernal Equinox and the Z direction is the CEP (Celestial Ephemeris Pole). That's good so far, provided that this Z direction doesn't move wrt to the stars (Celestial Sphere). Yet it does! WebLocations of objects in space can also be represented using Cartesian coordinates in an ECI frame. The gravitational attraction of the Sun and Moon on the Earth's equatorial bulge …

Even though Skyfield scripts often produce output in spherical coordinates — like right ascension and declination, or altitude and azimuth — Skyfield always stores positions internally as Cartesian (x,y,z) vectors oriented along the axes of the International Celestial Reference System (ICRS).The ICRS is a higher-accuracy …
Web• The method to precess coordinates to a new equinox is a common approach to coordinate transforms • The general approach is to define (and measure) a rotation matrix, R that transforms between systems as – (x 2,y 2,z 2) = (x 1) R (y 1) (z 1) • e.g., to precess coordinates from B1950 to J2000:
