As in other standard laboratory, the time & frequency produced in the laboratory is traceable to UTC by using GPS Common View Method. A single channel GPS Time Transfer System is programmed to follow BIPM Schedule for East Asia region. The other is a multi channel type, based on modular Motorola Oncore GPS engine, developed under the collaboration with NMIA Australia. The system is controlled by a PC that has an optional direct hot-line connection with the NMIA for maintenance.






Data on BIPM GGTTS format, and other laboratory timing data are available here

GPS Common View is one of various method used for building International Time Link and Key-Comparison coordinated by BIPM. The laboratory also propose to use GLONASS Common View System as a second system. This will make the laboratory able to evaluate and  minimize or eliminate biased systematical error that may be introduced in a time-transfer system.
