초록

GPS Common-View 방식에 의해 원거리의 기분클럭에 위상동기되는 원격지 동기 시스템을 설계하고 제작하였다. 이원격지 동기 시스템의 측정결과 $10^{-12}$의 주파수 정확도를 유지하였으며 ITU-T 의 권고(G.811)를 만족하는 MTIE 특성을 보여주었다. 현재 전체적으로 자동화 기능을 갖는 초기모델이 구현되었으며 가까운 시일 내에 통신망 동기용으로 사용 될 수 있으리라 기대된다.

A remotely located synchronization system which is locked to the remote master clock has been implemented by using GPS Common-View technique. The measurement results showed that the accuracy of the remote synchronization system could be kept within a few parts in $10^{-12}$ and MTIE(Maximum Time Interval Error) met the ITU-T Recommendation(G.811). A prototype system having fully automatic operational functions has been realized up to now and is expected to be used in the network synchronization in the near future.
