Research on the relation between frequency stability and timekeeping clock allocation

Through analyzing the demands of the timescale stability for small or medium-size time laboratory, it is researched that the relationship between different allocation of clock set and stability of time scale with the data of atomic clock 5071A, which is mainly used atomic clock for time keeping at present, released by the Bureau International des Poids et Mesures; Weight is one of the keys to atomic timescale algorithm. Based on the statistical analysis of the timescale calculation results obtained by different quantity clocks and different weights, a principle of determining clock weight which is suitable for small or medium-sized time laboratory is put forward.
