The base station clocks output clock frequency signals. The preprocessing module is connected with the base station clocks, and the preprocessing module is connected with the unified reference source. The receiver obtains satellite signals. The clock difference calculation module is connected with the preprocessing module, the clock difference calculation module is connected with the receiver, and the clock difference calculation module is connected with the unified reference source. The model calculation module is connected with the clock difference calculation module. The timing prediction output module is connected with the model calculation module, and the calculation data is transmitted through the model calculation module to the timing prediction output module to be used as timing prediction clock output. The technical effect of high-precision timing is achieved.

Description

technical field [0001] The invention belongs to the technical field of clock timing, in particular to a comparison-based clock timing device. Background technique [0002] Time is one of the seven basic physical quantities in physics (length m, time s, mass kg, thermodynamic temperature K (open), current unit A (ampere), light intensity cd (candela), and the amount of matter mol (mole)). one. As a basic physical quantity, time is directly related to the basic scientific research of a country, the stable operation of the national economy and all aspects of national defense construction. [0003] In the existing clock-based timing technology, the time reference is recognized as the most accurate time scale. However, due to the limited number of time references, various countries continue to strengthen the time and frequency sources while developing high-precision time and frequency sources. Research on timing technology. For example, as a new type of time service system, th...
