Stream C: Ground Penetrating Radar (GPR)


Stream C


High Productivity: surveys only need to be performed in one direction to ensure optimal detection of both longitudinal and transversal pipes;

No advanced training needed: the system automatically detects and locates the position of pipes in real time and displays them on screen;

Reduced user fatigue: thanks to electronic ride height adjustment and a motor assisted drive wheel;

Facilitates large surveys: the system can be towed manually or with a small vehicle, increasing the acquisition speed (up to 6 km/h).



Stream C is the compact array solution for real-time 3D mapping of underground utilities and features. Thanks to the increased level of accuracy provided by a massive antenna array, Stream C is able to detect pipes and cables automatically.

Daily use of Stream C is aided by ergonomic features including electronic ride height adjustment, options to tow manually or with a small vehicle and a motor assisted drive wheel.

Stream C is available in both Basic and Advanced configurations.


 Stream C
  • Massive array of 34 antennas in two polarizations: this enables an accurate 3D reconstruction of the underground utility network to be 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 hardwearing 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: pipes, cables and buried objects can be automatically transferred to CAD and GIS formats, allowing a complete subsurface GIS based digital map to be quickly produced.

Stream C is supplied with the OneVsion and GRED HD 3D CAD software suites.


OneVision is a new software application for advanced GPR data collection, which provides real-time target viewing, onsite object mapping and GPS navigation. It is a powerful tool for use with an array of antennas when performing utility mapping, archeological and environmental surveys and extensive mapping of medium to large size projects.

OneVision is available for:

  • Stream C
  • Stream EM
  • Stream X
  • RIS MF Hi-Mod

OneVision is a powerful application for advanced surveys with integrated navigation, providing:

  • Real-time tomography on a cartographic background (e.g. Google Maps, GeoTIFF and KML);
  • Multi-view screen with GPR radar maps (B-scan and T-scan), radar tomography (C-scan) and cartography;
  • Survey planning tools;
  • Special optional ADP Tool for the Stream C that provides automatic pipe detection;
  • Continuous monitoring of GPR and GPS statuses;
  • Survey management with interactive and on-site target mapping as well as review and editing.

OneVision provides increased productivity and reduced costs:

  • Real-time on-site detection allows immediate decision making;
  • OneVision aids target recognition removing the need for specialist skills;
  • Provision of the tomographic map in real time ensures immediate understanding of complex environments e.g. urban areas;
  • OneVision’s integrated acquisition and navigation functions ensure that complete coverage is always provided in a single visit.



GRED HD 3D CAD is specifically designed to offer an integrated framework for CAD and GIS, combining the characteristics of industrial productivity with high levels of reliability. It also offers unique features such as the creation and display of 2D and 3D tomograms in just a few minutes after the basic filtering of the raw data and the direct export of structures and objects of any generic shape to CAD or GIS maps.

The software is fully compatible with any GPS or positioning data in order to obtain automatically geo-referenced data plots.

Key features include:

  • Real-time display of trajectories using GPS or Total Station.
  • 2D and 3D tomography for an immediate visualization and detection of anomalies.
  • Automated transfer to CAD/GIS: the identified target can be automatically transferred to CAD or GIS maps for professional SUE / utility mapping.
  • Geolocated data information and visualization
