Fixed Wing Surveys

We are a small company and only operate one field project at a time so that all our attention is focused on your survey. Our senior geophysicist with over 30 years of airborne experience is in the field processing your data. Your survey and satisfaction are our number one priority. TAS offers the following services in a fixed-wing platform:

High Resolution Surveys

Magnetics
Horizontal Magnetic Gradient
Radiometrics
VLF-EM

Applications

base and precious metal exploration
kimberlite exploration

Processing

Oasis Montaj and custom routines for geophysical data processing
C3NavG2 and HeadRT+ for post flight GPS processing
Praga4 full spectrum radiometric processing
Nelson method of calculating a residual magnetic field from the diurnal free horizontal gradients for shallow magnetic sources. This eliminates any downtime for diurnal activity.
In-field processing for next day preliminary grids
