get_icrf_position_vector
========================

.. py:function:: pride.astro.get_icrf_position_vector(target: str, epochs: numpy.ndarray) -> numpy.ndarray

   Get cartesian position vector of a target in ICRF (SI units)

   Uses spice.spkpos to get the position of a target in J2000, with respect to SSB, and with aberrations set to NONE. The output is transformed to SI units and casted to an (N, 3) numpy array.

   :param target: Target name known by spice
   :param epochs: Array of epochs in ET (TDB seconds past J2000)
   :return position_vector: Aberrated, cartesian position vector of the target with respect to SSB in J2000 (ICRF) frame.
