Ab sofort tragen vier primäre Atomuhren aus der PTB zur Weltzeit bei

Neue Caesium-Fontänenuhr CSF2 wird in den kleinen internationalen Club der primären Uhren aufgenommen

(PresseBox) (Braunschweig, )
Die besten Caesium-Atomuhren der Welt steuern die Koordinierte Weltzeit UTC (Universal Time Coordinated), eine Atomzeitskala, die die Grundlage für die im täglichen Leben verwendeten Zonenzeiten bildet. Aber auch bei der Navigation (GPS), der Astronomie, der Telekommunikation, der Erdvermessung und in der physikalischen Grundlagenforschung sind exakte Zeittakte von großer Wichtigkeit. Bisher waren drei Uhren der Physikalisch-Technischen Bundesanstalt (PTB) Mitglied dieses exklusiven Clubs der primären Caesium-Atomuhren, nun ist eine vierte hinzugekommen: die Caesium-Fontänenuhr CSF2. Ihre Daten werden in diesem Monat erstmals zur Bestimmung von UTC mit berücksichtigt. Damit sind die PTB und das französische Zeitinstitut weltweit die einzigen Institute mit vier primären Odocnnzev.
