| Abstract: | The satellite-TV time signal comparison system set up at NTSC(National Time Service Center)is introduced briefly.The methods to detennin the time delay of the time signals inserted into the CCTV signals,which are transmitted only by satellites or relayed by local TV station as well,with the time sig- nal comparison system are presented and the measuements are analysed,being of referential value to timing users. |
