Abstract

The embodiment of the invention discloses a satellite two-way-based remote time reproduction system, which comprises a standard comparison device and a remote reproduction device; the remote reproduction device is configured to execute the following steps: S1, receiving a processed first comparison signal output by the standard comparison device, and comparing the first comparison signal with a local signal of the remote reproduction device; s2, if the comparison result meets a preset comparison condition, outputting a first comparison signal as a reproduction signal; if the comparison resultdoes not meet the preset comparison condition, generating a second comparison signal based on the comparison result and outputting the second comparison signal to a standard comparison device; s3, receiving a second comparison signal processed by the standard comparison device, and comparing the second comparison signal with a local signal regenerated by the remote reproduction device; if a comparison result meets a preset comparison condition, outputting the processed second comparison signal as a reproduction signal; and if the comparison result does not meet the preset comparison condition,repeatedly executing the steps S1-S3 again until a reproduction signal meeting the preset comparison condition is output.

Description

technical field [0001] The invention relates to the field of time reappearance, and more specifically, relates to a satellite-based two-way remote time reappearance system. Background technique [0002] Satellite two-way time comparison technology uses communication satellites as the carrier, and uses pseudo-code ranging technology to realize long-distance and high-precision clock error measurement. It has high measurement accuracy and good real-time performance, and is widely used in time-frequency measurement, navigation and other fields. At present, the requirements for time consistency are getting higher and higher, so the remote precision reproduction of time is particularly important. Generally speaking, the remote reproduction of standard time can be realized by means of satellite time service, long-wave time service, etc., but because this type of time service method introduces more errors, the accuracy of time reproduction is low, and it can only reproduce a specifi...
