Data Acquisition Units - Overview

There are currently 3 seismic data acquisition units in the ISS stable.

The Geophysical Seismometer (GS) enjoys an extremely high dynamic range with a wide choice of sampling rates, and is the basis of ISS real-time or off-line seismic monitoring networks. The GS can be used in a network of stand-alone mode of operation. See Typical Applications for examples.

The intrinsically safe GSi can be used for mine-wide real-time seismic monitoring in explosive prone mines, such as most underground coal mines.

The counting seismometer GSx is based on small self-contained units that communicate via a wireless ad hoc network to provide infrastructure-less extensions to existing real-time seismic networks. Each unit will pre-process seismic signals to provide statistical data about local micro-fracture populations and hence enable personal seismic safety monitors.
