Time and frequency

Service

VSL provides the most accurate calibrations in the field of time and frequency in The Netherlands. This is possible because VSL is responsible for maintaining the national time and frequency standard. VSL also provides synchronisation services in the form of a ‘Time Service Bulletin’and for computers via the Internet. These services ensure reliability and quality assurance within a wide range of applications.

Method

The national time and frequency standard maintained at VSL is based on four atomic clocks. These clocks are included in a worldwide network, which jointly determines the international time scale (UTC) and the duration of the second. VSL uses frequency dividers and multipliers to achieve an extensive frequency range.

Application and clients

Time and frequency are widely used quantities in daily life. They are used in various industrial processes, electronic data integrity systems, telecommunication, astronomy, geodesy, navigation, medical research, and for leisure time activities, e.g. sporting events. Clients are therefore found in a wide application field, such as manufacturers and suppliers of frequency and time measuring instruments, research institutes, defence, telecom and Internet providers and banks.
