Common View
The time difference between two clocks may be determined by simultaneously comparing each clock to a common reference signal that may be received at both sites. As long as both end stations receive the same satellite signal at the same time, the accuracy of the signal source is not important. The nature of the received signal is not important, although widely available timing and navigation systems such as GPS or LORAN are convenient.
The accuracy of time transferred in this way is typically 1–10 ns.

Famous quotes containing the words common and/or view:
“In all conversation between two persons, tacit reference is made, as to a third party, to a common nature. That third party or common nature is not social; it is impersonal; is God.”

“I’ll view the manners of the town,
Peruse the traders, gaze upon the buildings,
And then return and sleep within mine inn,
For with long travel I am stiff and weary.”
