High Resolution Airborne Geophysics

VTEM

Geotech's proprietary VTEM is the leading time-domain electromagnetic system in the world. The coincident, vertical dipole transmitter-receiver configuration provides a symmetric system response. Any asymmetry in the measured EM profile is due to the conductor dip, not the system or direction of flying. This allows for easy identification of the conductor location and for interpretation of the EM data. The low noise receiver, plus the high power transmitter yields a low noise system that has the best signal-to-noise ratio of any airborne survey system available commercially.

  • Over 2,000,000 line-kms flown
  • Best signal-noise levels
  • System most often selected by clients to fly airborne EM surveys
  • Three diameters to select from based on the terrain and desired depth of penetration
  • Adjustable Dipole Moments 250,000 NIA over 2.5 Million NIA
  • Single mag or horizontal mag options
  • Adjustable pulse width
