Node-based Seismometer Cloud-connected Seismograph Multi-channel Seismic Recorder

Node-based Seismometer Cloud-connected Seismograph Multi-channel Seismic Recorder ​

Overview:

The Node-based Digital Seismometer represents a leap in passive-source seismic acquisition, integrating high-sensitivity single-component velocity sensors with 24-bit AD conversion for unparalleled signal fidelity.

Key Specifications:

1. Frequency Bandwidth Options:

   • GD-A1: 1s–200Hz (ideal for shallow crustal studies).

   • GD-E20: 20s–150Hz (suited for deep mantle profiling).

   • 
     

2. Performance Metrics:

   • Dynamic Range: 120dB ensures capture of weak signals amid noise.

   • Amplitude Consistency: <5% cross-channel variance for reliable array data.

   • 
     

3. Noise Floor: Exceeds global standards (NHNM/NLNM curves) across all bands.

Operational Advantages:

• Autonomous Deployment: Integrated GPS/BDS timing (5×10⁻⁸ stability) enables precise synchronization.

• Modular Design: Hot-swappable battery packs (480-hour lifespan) and storage modules.

• Cloud Integration: Optional jOPENS/Blazer systems support real-time QC via WiFi/Ethernet.

Applications:

• Resource Exploration: High-density 3D imaging for hydrocarbons/coal.

• Geotechnical Monitoring: Long-term microtremor analysis for seismic hazard assessment.

• Academic Research: MiniSEED/SAC compatibility aligns with IRIS standards.
