What is GD-3C Nodal SeismographTriaxial Broadband Seismic Recorder
Seismic Node ?
The GD-3C Node is a small, light-weight seismograph node. Designed
for "set and forget" data acquisition, the GD-3C node meets and
exceeds all seismograph requirements.
GD-3C Nodal Seismograph is a new generation smart seismic acquisition node used to connect
with external land and marsh geophone or hydrophone. It has
wireless QC functionality to enable a field deployment tool or
mobile phone to check for good status. This includes recording
parameters, battery voltage, temperature, remaining data storage,
GPS position and quality, connected sensor status and more.
