VLF Systems
The Very Low-Frequency (VLF) survey technique is a passive electromagnetic method that utilizes distant, globally positioned transmitters to induce secondary responses in conductive geologic units to determine overlying conductive materials in the subsurface. Systems available for UAV and airborne platforms.
