Embodiment Construction
[0027] The specific steps of a coarse synchronization method for satellite two-way time comparison are:
[0028] The first step is to build a satellite two-way time comparison system
[0029] Satellite two-way time comparison system, including: satellite two-way time comparison master station and satellite two-way time comparison slave station. Among them, the satellite two-way time comparison master station includes: master atomic clock, master time comparison modem and master satellite receiving and receiving earth station; satellite two-way time comparison slave station includes: slave atomic clock, slave time comparison modem, and satellite sending and receiving earth station station and coarse synchronizer. Coarse synchronization device, including: 1PPS splitter, phase micro-step module, two-to-one switch and control module.
[0030] At the satellite two-way time comparison main station, the 10MHz and 1PPS signals output by the main atomic clock are input to the referen...
