  • Choice of odometer
  • Operation of processing unit with an external battery > 12 hours

OKO-3 is a new high-performance generation of ground-penetrating radars, that ensures 3X faster sounding with increased quality of radargram. Built-in Wi-Fi module allows one to control GPR via tablets, smartphones and laptops — without deploying uncomfortable connecting wires.

Main features of new generation of GPR OKO-3:
  • Increased number of points in seismic trace (in depth) — up to 16 384
  • Increased sounding speed — up to 380 scan/s (at 512 points)
  • Improved radargram quality due to increase in accumulation
  • Built-in WI-FI in control unit to connect with a laptop, tablet or smartphone
  • Capability to connect GPS with control unit
  • Intelligent displacement sensor — sensor parameters are recorded in non-volatile memory and automatically set when turned on
  • Android version of Geoscan32 software for controlling GPR tablet and smartphone
Tasks that can be successfully solved with OKO-3:
  • Characterization of geological section
  • Search and evaluation of the state of underground communications: pipelines, cables, tunnels
  • Inspection of highways — determining the thickness of pavement layers, finding the causes of deviations and subsidence of roadbed
  • Study of railway embankments — inspection and flaw detection of roadways
  • Inspection of runways
  • Status monitoring of bridges — analyzing the state of reinforced concrete spans, determining the need of strengthening them, etc.
  • Inspection of buildings, determination of position and quality of reinforcement
  • Ecological inspections — search for areas of soil contamination, leakages of oil and gas pipelines
  • Archaeological studies — non-destructive search for ancient and modern natural and anthropogenic structures, objects and burials
  • Control of construction — picking layers, computing quantities of works
  • Detection of groundwater level, overwatering and decompression zones
  • Study of the bottom of water basins, differences in the composition of the soil bottom, mapping of bottom sediments and bottom topography
  • Determination of the thickness of ice cover
  • Determination of layer thickness of seasonal freezing or thawing, delineation of the areas of permafrost, taliks, etc.
  • Search for UXO and sunken equipment
