Stream EM

Description

Stream EM is a multi-channel ground penetrating radar solution dedicated to utility locating and mapping.

The solution has been developed to cover tens of hectares/day, obtaining the best utilities detection quality thanks to 40 separate channels. Stream EM includes double polarized (VV and HH) antennas to cover wide road surfaces. The system maintains the same maximum data collection speed, 15 Km/h, with only longitudinal scans for both longitudinal and transversal pipes detection.

Stream EM enables the user to map all underground utilities in large areas, delivering clear and accurate results across hundreds of Km2. The high number of antennas increases the quality of the data achievable.

The system can be easily disassembled for transport in a van size vehicle. It can also be reconfigured for mapping sidewalks and difficult areas / other applications such as archaeology, environmental, road/runway.

Stream EM Key Features:

  • Massive array of 40 antennas in two polarisations: A massive array of 40 antennas ensures a high sampling density. This results in accurate 3D modeling of the subsurface and ease of detecting buried targets and anomalies. The use of both polarisations provides optimal detection of main and junction pipes at the same time.
  • Speed: Stream EM can be towed by a car up to 15 km/h:
    • Survey many miles per day
    • Be operated by only two people
    • Run continuously without interrupting traffic
    • Keeps the crew safe inside the vehicle.
  • Accurate to less than 5cm: Stream EM can be interfaced with GPS or a total station to accurately geo-locate the surveyed area. All the pipes, cables and anomalies are detected with high accuracy and are individually distinguishable.
  • Professional Subsurface Utility Engineering (SUE) survey: Pipes, cables and buried object can be automatically transferred to CAD and GIS format with a proprietary software tool.

Benefits of Stream EM:

  • Improved management of underground utility design, relocation and coordination
  • 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
