Abstract
In order to solve problems of “jump second” when using only GPS for timing service and inconvenience of installing GPS antennas in some places, we propose a new algorithm combining GPS and NTP to adjust the local clock of an integrated accelerograph. The process flow of the method was described in detail, and the timing accuracy was tested. When the local clock is synchronized against the GPS time output, the time accuracy can reach to 10 s, while if it is only synchronized against NTP servers, we can obtain a time accuracy of 2 ms. Moreover, during the long run test of the system, we have not found the problem of “jump second”. Therefore, this method can effectively solve the problems when only using GPS for time service and the time accuracy can also meet the requirements of strong-motion observation on time precision.
