Time and frequency activities at the National Measurement Institute, Australia

The time and frequency group of the National Measurement Institute, Australia, (NMIA) maintains the Australian national standards for time of day and for frequency. Research and development activities of the group include: development of microwave frequency standards in the 10-15 accuracy range based on trapped Yb+ ions; development of GPS common-view time transfer systems, and the use of these systems to deliver traceable time and frequency to a client's premises by continuous remote calibration; two-way satellite time and frequency transfer; and time and frequency dissemination around Australia by means including the recently developed NMIA 'speaking clock' telephone service
