Abstract
This study developed a new cable-less seismograph system, which can transmit seismic data in real-time and automatically perform high-precision differential self-positioning. Combining the ZigBee technology with the high-precision differential positioning module, this new seismograph system utilized the wireless personal area network (WPAN) and real-time kinematic (RTK) technologies to improve its on-site performances and to make the field quality control (QC) and self-positioning possible. With the advantages of low-cost, good scalability, and good compatibility, the proposed new cable-less seismograph system can improve the field working efficiency and data processing capability. It has potential applications in noise seismology and mobile seismic monitoring.
Highlights
Compared with a cabled seismograph, cable-less seismographs have no complicated or bulky cables

For the shallow noise exploration (~1 km), the observation radius of the new cable-less seismograph was between tens to hundreds of meters, which met the requirements of the positioning range
