The GEOANT Ant-1C-5Hz is an advanced single-component nodal seismometer engineered to simplify seismic exploration with lower operational complexity, improved survey efficiency and significant project cost savings.

It integrates GPS/Beidou synchronization algorithms, ultra-low-power circuitry, and wireless data and charging technology. With high integration, extended operating life and zero external contacts, it supports intelligent and automated deployment in complex terrain and harsh environments.

Its state-of-the-art ADC architecture delivers exceptional dynamic range for reliable micro-vibration detection, and it supports UAV-assisted surveys at altitudes above 300 meters AGL.

Recommended applications:

  • Seismic zonation and safety assessment
  • Shallow geological surveys
  • Urban subsurface exploration
  • Geothermal exploration
  • Coal mine goaf detection
  • Oil, natural gas, coal and nonferrous mineral exploration

Its compact deployment-ready format helps teams improve productivity while maintaining rugged field reliability.
