The Standard Time and Frequency Signal (STFS) is a time signal service available in the United States which provides standard time and frequency signals, broadcast on very precise carrier frequencies by the U.S. Naval Observatory and the National Institute of Standards and Technology (NIST), formerly the National Bureau of Standards (NBS).
A similar service is operated in the United Kingdom by the National Physical Laboratory, broadcasting from Anthorn radio station in north-west England, and by the BBC using the 198kHz carrier of the Radio 4 national radio station with a frequency accuracy of 1 part in 1011.
The National Physical Laboratory, India is the premier research laboratory in India in the field of physical sciences. NPLI continues to disseminate standard time and frequency signals (STFS) via geostationary satellite INSAT with an accuracy of 10 ms.
Famous quotes containing the words standard, time, frequency, signal and/or service:
“A disposition to preserve, and an ability to improve, taken together, would be my standard of a statesman.”
—Edmund Burke (1729–1797)
“Time rushes by and yet time is frozen. Funny how we get so exact about time at the end of life and at its beginning. She died at 6:08 or 3:46, we say, or the baby was born at 4:02. But in between we slosh through huge swatches of time—weeks, months, years, decades even.”
—Helen Prejean (b. 1940)
“One is apt to be discouraged by the frequency with which Mr. Hardy has persuaded himself that a macabre subject is a poem in itself; that, if there be enough of death and the tomb in one’s theme, it needs no translation into art, the bold statement of it being sufficient.”
—Rebecca West (1892–1983)
“Mistakes, scandals, and failures no longer signal catastrophe. The crucial thing is that they be made credible, and that the public be made aware of the efforts being expended in that direction. The “marketing” immunity of governments is similar to that of the major brands of washing powder.”
—Jean Baudrillard (b. 1929)
“Old books that have ceased to be of service should no more be abandoned than should old friends who have ceased to give pleasure.”
—Peregrine, Sir Worsthorne (b. 1923)
