数字卫星电视共视时间比对

研究利用数字卫星电视进行共视时间传递的方法,选择利用电视信号中的PCR来完成时间的传递,分析利用数字卫星电视进行共视的基本原理,并从电视信号中提取相关信息的原理进行了说明。通过零基线的共钟比对试验得到接收机之间的时延差,进行远距离的共视时间比对试验,得到了一些比较有意义的结论。

Common-view Time Transfer based on Digital Satellite TV

This paper studied a method for common-view time transfer based on digital satellite television, choosing PCR of television signal to complete time transfer, analyzed fundamental principle to realize common view based on digital satellite television, and illustrated the principle to extract relevant information from the television signal. The delay difference between receivers is obtained by co-clock comparison test of zero baseline. Some meaningful conclusions are get by long-distance common view time comparison test.
