Reseña del editor

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Time from NPL is a radio signal broadcast from the Anthorn VLF transmitter near Anthorn, Cumbria which serves as the United Kingdom''s national time reference. The time signal is derived from three atomic clocks installed at the transmitter site, and is based on time standards maintained by the UK''s National Physical Laboratory in Teddington. The service is provided by VT Communications under licence from the NPL and is funded by the Department for Innovation, Universities and Skills. The signal, also known as the MSF signal is broadcast at a highly-accurate frequency of 60 kHz and can be received throughout the UK, and in much of northern and western Europe. The signal''s carrier frequency is maintained at 60 kHz to within 2 parts in 1012, controlled by caesium atomic clocks at the radio station.
