  • Constructor Details

    • FieldGeodeticPoint

      public FieldGeodeticPoint(T latitude, T longitude, T altitude)
      Build a new instance.

      The angular coordinates will be normalized so that the latitude is between ±π/2 and the longitude is between ±π.

      Parameters:
      latitude - latitude of the point (rad)
      longitude - longitude of the point (rad)
      altitude - altitude of the point (m)

    • FieldGeodeticPoint

      public FieldGeodeticPoint(Field<T> field, GeodeticPoint geodeticPoint)
      Build a new instance from a GeodeticPoint.
      Parameters:
      field - field to which the elements belong
      geodeticPoint - geodetic point to convert

  • Method Details

    • getLatitude

      public T getLatitude()
      Get the latitude.
      Returns:
      latitude, an angular value in the range [-π/2, π/2]

    • getLongitude

      public T getLongitude()
      Get the longitude.
      Returns:
      longitude, an angular value in the range [-π, π]

    • getAltitude

      public T getAltitude()
      Get the altitude.
      Returns:
      altitude

    • getZenith

      public FieldVector3D<T> getZenith()
      Get the direction above the point, expressed in parent shape frame.

      The zenith direction is defined as the normal to local horizontal plane.

      Returns:
      unit vector in the zenith direction
      See Also:

    • getNadir

      public FieldVector3D<T> getNadir()
      Get the direction below the point, expressed in parent shape frame.

      The nadir direction is the opposite of zenith direction.

      Returns:
      unit vector in the nadir direction
      See Also:

    • getNorth

      public FieldVector3D<T> getNorth()
      Get the direction to the north of point, expressed in parent shape frame.

      The north direction is defined in the horizontal plane (normal to zenith direction) and following the local meridian.

      Returns:
      unit vector in the north direction
      See Also:

    • getSouth

      public FieldVector3D<T> getSouth()
      Get the direction to the south of point, expressed in parent shape frame.

      The south direction is the opposite of north direction.

      Returns:
      unit vector in the south direction
      See Also:

    • getEast

      public FieldVector3D<T> getEast()
      Get the direction to the east of point, expressed in parent shape frame.

      The east direction is defined in the horizontal plane in order to complete direct triangle (east, north, zenith).

      Returns:
      unit vector in the east direction
      See Also:

    • getWest

      public FieldVector3D<T> getWest()
      Get the direction to the west of point, expressed in parent shape frame.

      The west direction is the opposite of east direction.

      Returns:
      unit vector in the west direction

      public GeodeticPoint toGeodeticPoint()
      Get non-Field equivalent.
      Returns:
      geodetic point
