Station
=======

.. py:class:: pride.experiment.Station(name: str, id: str | None = None)

   VLBI station

   Attributes
   ----------
   name :
       Station name
   possible_names :
       Alternatives names for the station


   .. py:method:: from_experiment(name: str, id: str, experiment: pride.experiment.experiment.Experiment, uplink: bool = False) -> Station
      :staticmethod:



   .. py:method:: tectonic_corrected_location(epoch: astropy.time.Time) -> astropy.coordinates.EarthLocation

      Station coordinates corrected for tectonic motion



   .. py:method:: location(epoch: astropy.time.Time, frame: Literal['itrf', 'icrf'] = 'itrf') -> numpy.ndarray

      Time-dependent station coordinates

      Returns cartesian coordinates of the station at a set of UTC epochs. The position includes the best available correction, which is determined based on the has_geophysical_corrections (G) flag.
      - G=True: Position is corrected for tectonic motion and all the geophysical displacements specified in the configuration file.
      - G=False: Position is corrected for tectonic motion only.

      :param epoch: UTC epochs at which to calculate the station coordinates
      :param frame: Reference frame for the coordinates: ITRF or GCRS
      :return: Station coordinates as (N, 3) array



   .. py:method:: velocity(epoch: astropy.time.Time, frame: Literal['itrf', 'icrf'] = 'itrf') -> numpy.ndarray

      Time-dependent station velocity

      Returns cartesian velocity of the station at a set of UTC epochs. The velocity is only available after the station has been updated with geophysical displacements.

      :param epoch: UTC epochs at which to calculate the station velocity
      :param frame: Reference frame for the velocity: ITRF or GCRS
      :return: Station velocity as (N, 3) array
