Can perform the entire cycle of gravimetry operations:

  • designing of operations;
  • organizational provision of field studies;
  • high-precision gravity survey;
  • horizontal-vertical positioning of geophysical measurements;
  • interpretation of geophysical data;
  • integration of geological-geophysical information into GIS projects;
  • compilation of gravity maps.

Gravity group is equipped with the state-of-the-art gravimetry and satellite instrumentation of geodetic class, all-terrain vehicles and snowmobiles, field equipment as well as it has qualified specialists with a big experience of field and laboratory operations.

Gravimetrical equipment
Automated gravity meters AUTOGRAV CG-5 «Scintrex»

These instruments are today the highest accuracy ones in the class of gravity meters measuring gravity increments between observation stations.

The main technical parameters of CG-5 gravity meters are as follows:

  • resolution: 0.001 mGal;
  • error: 0.005 mGal;
  • measurement range: about 8000 mGal;
  • temperature compensation (thermostating);
  • low residual drift of the instrument;
  • data accumulation and averaging with a resolution of 1 measurement per second;
  • filtering of “spikes”;
  • continuous correction of inclination;

  • corrections for tidal gravity variations;
  • memory up to 12 MBytes.

Satellite geodetic equipment
Trimble R7 GNSS

  • Measurement accuracy – a few cm.
    Satellite measurements are made in differential mode at a distance away from the base station up to 25 km.
  • GPS data are processed in “post-processing” mode.
  • Thanks to the described GPS instrumentation, forest cutting - down is excluded and the traditional methods of horizontal-vertical positioning are not practically used.

Work experience

Gravity party has work experience in surface gravity survey on a scale 1:200 000 - 1-1000. Works were carried out as an avialanding method by helicopters MI-8 and Mi-2, and in a land variant (cross-country vehicles Avenger, snowmobiles Lynx, ski and foot shooting). Experts of party in 1993-2009 perform works on geological mapping, to searches of ore mineral deposits and hydrocarbonc raw materials in areas: Taimyr peninsula, the Tyumen region, the Volga region, Republic Komi, Krasnoyarsk region, Mongolia.
