Two-Way Satellite Time and Frequency Transfer
Encyclopedia
Two-way satellite time and frequency transfer (TWSTFT) is a high-precision long distance time and frequency transfer
mechanism used between time bureaux to determine and distribute time and frequency standards.
TWSTFT is being evaluated as an alternative to be used by the Bureau International des Poids et Mesures in the determination of International Atomic Time
(TAI), as a complement to the current standard method of simultaneous observations of GPS transmissions.
Time and frequency transfer
Time and frequency transfer describes mechanisms for comparing measurements of time and frequency from one location to another. The technique is commonly used for creating and distributing standard time scales such as International Atomic Time ....
