class astropy.coordinates.ITRS(*args, **kwargs)[source] [edit on github]

Bases: astropy.coordinates.BaseCoordinateFrame

A coordinate or frame in the International Terrestrial Reference System (ITRS). This is approximately a geocentric system, although strictly it is defined by a series of reference locations near the surface of the Earth. For more background on the ITRS, see the references provided in the See Also section of the documentation.

Note that this frame does not have an obstime, because it is rotating with the Earth.
