Abstract :
The Japanese Quasi-Zenith Satellite System (QZSS) offers the possibility to transmit information with unprecedented bit rates via the L-band experimental (LEX) signal. This feature can be used to disseminate Japan Standard Time, i.e. UTC(NICT) to any user who is capable to receive the new QZSS signal. Various modes for the transmission of the timing information as well as a dedicated ionosphere correction model allow the users to instantaneously realize UTC(NICT) across Japan with an uncertainty of a few nanoseconds.
