摘要
A clocking device of substantially constant stability for short-term and long-term measurements. This clocking device comprises first generators of a clocking signal with substantially constant stability for short-term measurements, and second generators of a clocking signal of constant stability for long-term measurements. Means for the automatic locking of one of the said first or second clocking signals to the other clocking signal are provided, and enable the automatic frequency and/or phase locking of said signals. The automatic locking means have a time constant corresponding to the transition zone between the short-term and long-term measurements. The device can be applied in the high-precision time-measuring instruments industry and to air and space navigation instruments.
