Complex airborne geophysical surveys (CAGS) are the most effective method of investigation for large-sized hard-to-reach areas.
Combined measurements of magnetic field, gamma-ray spectrum and transient EM-field (aero-TEM) provide reliable base for the subsequent geological interpretation of field data.
For the data processing of EM soundings data the brand new software and mathematical means are used, including means of full-fledged 3D - reconstruction of structure of the geological media that significantly increases the reliability of geophysical forecast.
The difference of “Impuls-A” platforms over some widespread analogs is two-step excitement of EM field used for increase of the amplitude of a spectrum of sounding impulses in the area of high frequencies that allows to parametrize the top part of a section in more detail.
For providing of magnetic surveys modern magnetometers on the basis of CS-3 and CS-L (Scintrex) magnetic field sensors are used. There is also a capability of providing of high-precision magnetic gradiometry on the basis of GSMP-30GA magnetometer-gradiometer.
For providing of airborne gamma-ray spectrometry digital 1024-channel scintillation RSX-4 and RSX-5 (RSI, the RS-500 series) spectrometers with a total volume of detectors up to 48 L are used.
