Reichweite des Senders DCF77

Der Sender DCF77 ist für die Physikalisch-Technische Bundesanstalt (PTB) weiterhin das wichtigste Medium, die gesetzliche Zeit für Deutschland zu verbreiten. Europaweit empfangen Millionen von Funkuhren die auf 77,5 kHz ausgestrahlten Zeitzeichen. DCF77 ist seit vielen Jahrzehnten ein bedeutender Teil der technischen Infrastruktur des Landes. Ohne ihn würden die Zeitanzeigen auf Bahnhöfen, Flughäfen und in Rundfunk- und Fernsehanstalten nicht funktionieren. Unternehmen der Versorgungswirtschaft (Elektrizität, Gas, Wasser) und im Telekommunikationssektor nutzen den DCF77 für die Steuerung und Überwachung ihrer Systeme. Umso wichtiger ist die zuverlässige Bereitstellung der Signale und ihre Überwachung durch die PTB. Mit den laufenden Modernisierungen der Anlage und ihrer unschlagbaren Einfachheit und Zuverlässigkeit ist die Zeitaussendung über Langwelle immer noch sehr zeitgemäß.

Advanced manufacturing (Symbolbild)

The production sector is the backbone of Europe’s industry with about 2 million companies and more than 30 million people working in this area. According to the EU, about half of all research funds are spent in this sector. There is certainly plenty of scope for research in this field: on the central challenges of digitalization and sustainability, for example. And metrological issues play a crucial role here too. To be able to bring together and promote metrological capacities, the European Association of National Metrology Institutes (EURAMET) has founded a European Metrology Network (EMN) for Advanced Manufacturing. Acting coordinator is Harald Bosse of the Physikalisch-Technische Bundesanstalt (PTB).

Evaluations

Evaluation report (in Geman only)
Stand: Januar 2012

In 2002, PTB as a whole was evaluated – with an excellent outcome. In 2008, an evaluation of PTB research followed, carried out by the Wissenschaftsrat (German Council of Science and Humanities) with a subsequent Implementation Report in 2012. You will find more about this at Opens internal link in current windowPTB in the World of Research or in the pdfs of the evaluation reports which you can download in the right-hand column.

The next evaluation will follow in 2016.
