| Abstract: | In recent years, as well as being used in deep seismic sounding, PDS seismographs are also used in ultra-dense seismic array observations and ambient noise imaging. Unfortunately, while PDS seismographs have no real-time GNSS time synchronization service, it is critical to get seismic data with high-accuracy sampling time. This paper introduces the hardware and firmware design of a new GNSS-synchronized automatic device based on microcontroller Apollo2. Through laboratory testing and field experiments, this time synchronization and automatic control device for PDS seismographs can well meet the needs of ultra-dense seismic array observations. |
