RISE is Sweden's NMI (National Metrology Institute) and, according to the Swedish constitution, is responsible for the central measurement quantities in the International System of Units, SI.
The main task of the time and frequency national standards laboratory is to distribute the Swedish standard time. This is conducted within the framework of national and international timekeeping, time synchronization, research and our calibration and development services.
One of the tasks of the national standards laboratory is to develop and disseminate methods of measurement within the area.
We perform research and development in areas such as time dissemination and time synchronization, with the help of fiber-optic communication systems, GNSS (Global Navigation Satellite Systems) and the Internet.
RISE provides several traceable services for time and frequency synchronization to various accuracy levels, by such means as GNSS, the Internet and the national Speaking Clock service.
We also offer calibration services and development of user-specific systems in the area.
