| Abstract: | By use of GPS (Global Positioning System) of PPS(Pulse Per Second) and precise timing circuit, multi\|station to measure lighting electric\|magnetic radiation pulse is synchronized. The error of precise timing circuit caused by crystal oscillator frequency excursion is also solved. The synchronizing precision can be 50 ns. In this paper, the synchronizing system data obtained in the field experiment is described.The reliability of this system is also verified. |
