Time and FrequencyThe main duty of the time and frequency national standards laboratory is to distribute the Swedish standard time. This is done within the framework of national and international timekeeping, time synchronisation, research and our calibration and development services.
One of the duties of the national standards laboratory is to develop and disseminate methods of measurement within the sector.
Time transmission and time synchronisation
We perform research and development in areas such as time transmission and time synchronisation, with the help of fibre-optic communication systems, GNSS (Global Navigation Satellite Systems) and the Internet.
Traceability and calibration
SP provides several traceable services for time and frequency synchronisation to various accuracy levels, by such means as satellite transmission, the Internet, telephone modems and the national Speaking Clock service.
We also offer calibration services and development of user-specific systems in the sector.
