mubody.coordinates.transformations.ICRF_to_ROT(t, r, v, frame_rot, eph)#

Transforms the position and the velocity from an inertial frame to a rotating frame.

Parameters:
  • t (1D-array) – Instants of interest

  • r (ndarray (3,)/(3, n)) – Position in the inertial frame

  • v (ndarray (3,)/(3, n)) – Velocity in the inertial frame

  • frame_rot (RotatingFrame class) – Source rotating frame

  • eph (Ephemeris class) – Ephemeris class

Returns:

  • rf (ndarray (3,)/(3, n)) – Position in the inertial frame

  • vf (ndarray (3,)/(3, n)) – Velocity in the inertial frame
