Stability and Accuracy of the International Atomic Time

Status of the International Atomic Time Tai

“…This explanation was confirmed by the a g r e e m e n t with other frequency standards, then by the p r i m a r y clocks. It i s a l s o supported by the sensitivity of t h e d r i f t of t ~m e s c a l e s based on industrial cesium clocks on the type of algorithm which i s used for t h e i r derivation (8). As long a s this drift p e r s i s t s regularly, i t can be easily compensated and it i s not a m a j o r difficulty in establishing TAI.…”

Time Transfer Methodologies for International Atomic Time (TAI)

“…The first step in this process is to generate the free atomic time scale (EAL). EAL is defined using the ALGOS algorithm [7][8][9] as:…”
