Services

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 two principals are in the field collecting and processing your data. Your survey and satisfaction are our number one priority. TAS offers the following services:

Fixed Wing High Resolution Surveys


• Magnetics
• Horizontal Magnetic Gradient
• Radiometrics
• VLF-EM

Applications


• base and precious metal exploration
• kimberlite exploration
• uranium exploration
• geological mapping
• oil and gas exploration

Survey parameters


• detailed surveys with line spacing as close as 50 m.
• survey heights as low as 120 ft. in treeless terrain
• survey speeds of 50 to 75 mps (90 to 150 kts)
• up to 7 hour endurance
• high-resolution cesium magnetometers sampling at 10 or 20  times/sec
• real-time DGPS navigation system sampling at 2Hz
• digital flight path videos
• 256 channel gamma-ray spectrometer with 33.4 litres (2048 cu. in.) of downward crystals and 4.2 litres of upward crystal

Processing


• Oasis Montaj and custom routines for geophysical data processing
• C3NavG2 and HeadRT+ for post flight GPS processing
• Praga3 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
