astroforge.coordinates.ITRSToSEZ(X, X0, lat, lon)[source]#

Converts cartesian vector in the International Terrestrial Reference System (ITRS) to a South-East-Zenith (SEZ) relative to a specific geodetic location.

Parameters:

X (NDArray[np.float64]) – Vector to be rotated, in ITRS (km)
X0 (NDArray[np.float64]) – Reference location, in ITRS (km)
lat (float) – Geodetic latitude of the reference location (degrees)
lon (float) – Longitude of the reference location (degrees)

Returns:

Rotated vector in SEZ coordinate frame

Return type:

NDArray[np.float64]
