Detection of its odd-parity patterns, B-modes, on a large angular scale is a smoking-gun signature of the inflationary universe. The radio telescope, GroundBIRD, employs one thousand of superconducting detectors. To obtain high performance from the detectors, it is important to eliminate an effect of detector&#8217;s baseline fluctuation (1\/f noise); this effect is four orders of magnitude higher than the B-modes. High-speed periodic motion of telescope&#8217;s line of sight, i.e., &hellip;"}
