| Abstract: | The real time seismic data of 47 seismic stations are transferred to the NCDSN (National Center of Digital Seismic Network) by VSAT satellite. The real time seismic data are split into three copies and received by seven computers, which backup each other. Theses seven computers are designed in two binds of configuration. One configuration is that 47 seismic stations are divided into three groups: Northeast, Southeast and Northwest. The other configuration is that 47 seismic stations are treated as one group. |
