Xcite™ TDEM

Xcite™ is a new generation of helicopter-borne time-domain electromagnetic (TDEM) systems developed by New Resolution Geophysics (NRG™). AXIOM is proud to be an exclusive provider of this service in North America.

By incorporating the latest new-age, high-speed electronics and sophisticated aeronautical engineering, the Xcite™ system is a new and innovative approach to geophysical surveying.

This state-of-the-art technology provides an efficient alternative to all prior TDEM technologies for the minerals exploration and geoscience mapping community—helping you boldly discover.

Xcite™ can detect, locate and map:
  • Mineral deposits
  • Aquifers
  • Aggregates
  • Fractures and faults
  • Saltwater encroachment
  • Paleochannels
  • Groundwater recharge
  • Water depths (bathymetry)
  • Oil and gas
  • Site characterization
  • Landslide investigations
  • Pre-construction planning

The Xcite™ system was developed using the latest technology by highly qualified and experienced engineers and geophysicists.

Key features of the system include:
  • Innovative patented loop design
  • Exceptional signal/noise
  • Excellent depth of investigation
  • Performance in both early and late times
  • Dipole moment up to 372,000 NIA
  • Logistically superior in setup and shipping
  • Time-Domain Electromagnetics
Xcite™ TDEM benefits:
  • All raw streaming data is recorded.
  • Time gates are selected post-flight, ensuring data presentations can be tailored to all target or application requirements.
  • Rapid setup time of only 2 hours for a complete system installation.
  • Mobilization costs are reduced due to the system’s compact size when deflated.
  • The shock-absorbing qualities of the frame result in a perfectly damped platform producing extremely quiet data or a semi-rigid system.
  • Extremely stable flight characteristics.
  • Field repairable Innovative design.
