Abstract: | It is shown that in the near future it will be possible to detect the dependence of the aberration constant on the direction to a star caused by our secular rotation. The corresponding corrections to the visible stellar positions will increase the accuracy in determining the Earth's rotation parameters by astro-optical means.
