A Realization of QZSS Time Synchronized with UTC(NICT)

SummaryThis paper describes a method of realizing QZSST (QZSS time) synchronized with UTC(NICT) in the planned update to a seven-satellite constellation QZSS to maintain PNT services in Japan. We expect uncertainties between QZSST and UTC(NICT) are small enough. Furthermore, we will confirm the realization of QZSST synchronized with UTC(NICT) through a demonstration lasting three years following the launch of the new satellites.
