State of the Art Technology: The Stream-C

  • High Productivity: Surveys only need to be performed in one direction to ensure optimal detection of both longitudinal and transversal pipes
  • Facilitates large surveys: The system can be towed manually or with a small vehicle, increasing the acquisition speed (up to 6 km/h).
  • Cost and time reductions: No need to block traffic or perform surveys at night
  • Increase in accuracy with a detection accuracy of as little as 5 cm
  • Increase productivity and have the ability to detect every buried target
  • Highly modular structure allows it to be reconfigured to map sidewalks and difficult to access areas
  • Massive array of 34 antennas in two polarizations: An accurate 3D reconstruction of the underground utility network is created in a single scan.
  • Automatic Pipe Detection (APD): Real-time automatic detection of buried pipes and cables.
  • Compact size: Stream C’s small dimensions enable it to survey areas inaccessible to larger array systems while maintaining the same accuracy.
  • Robust construction: Built to the highest standards and with robust materials so that it can be used in harsh, demanding environments.
  • 3D radar tomography: Real-time tomography on a GPS or total station assisted cartographic background.
  • Professional subsurface survey: Quickly produce subsurface GIS based digital maps when pipes, cables and buried objects are automatically transferred to CAD and GIS formats.
