| 抄録 | The Communications Research Laboratory (CRL) determines the national standard time and frequency in Japan, which is disseminated throughout Japan by the LF standard-time and frequency-signal emission, JJY. JJY is utilized as reference signal of radio controlled watches and clocks which have now come into wide use rapidly, and is being recognized as a social infrastructure which supports the people's living in Japan. In this paper, the following are introduced: JJY facilities with dual operation system, and future utilization and development of JJY. |
