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:
“Society’s double behavioral standard for women and for men is, in fact, a more effective deterrent than economic discrimination because it is more insidious, less tangible. Economic disadvantages involve ascertainable amounts, but the very nature of societal value judgments makes them harder to define, their effects harder to relate.”
—Anne Tucker (b. 1945)
“Had I but any time to lose,
On this I would it all dispose.
Cease Tempter. None can chain a mind
Whom this sweet Chordage cannot bind.”
—Andrew Marvell (1621–1678)
“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)
“This was a great point gained; the archdeacon would certainly not come to morning service at Westminster Abbey, even though he were in London; and here the warden could rest quietly, and, when the time came, duly say his prayers.”
—Anthony Trollope (1815–1882)
