For improving the quality of BPM signal and accomplishing the short wave time-service better, the BPM shortwave time-service transmission system has been updated by NTSC(National Time Service Centre). The composition and principle for the renovated BPM shortwave time-service transmission system are introduced in this paper. After nearly one year’s operation, the tests for the system show that the performance of BPM shortwave time-service transmission system has been greatly improved due to the upgrading of the transmission system.
