Abstract Synchronizing method between modules using wired line is well known and widely used. But, it is difficult to
adapt for huge construct like Solar Power Station/Satellite. We propose a novel synchronizing method between modules using
3tone signals. 3tone signals is transmitted from master transmitter. The synchronizing circuit in the modules outputs same
phase signal by digital signal processing. In this paper, we confirmed the new synchronizing method is available by simulation
and an examination. It is found out that the accuracy of the proposed system is within 1nsec by the examination.
