Preventing disasters with Ground Penetrating Radar

It Could Have Been Prevented!

What is Ground Penetrating Radar (GPR)

• Ground Penetrating Radar uses radio wave reflections (frequency from 25 MHz to 3,000 MHz) to collect information of underground or within a structure such as buried pipes, underground cavities, subsurface cracks, voids and layer thicknesses.

How does it Work

PPG/AAAA/nnn all rights reserved 26

Radargram

Opera Duo a first class underground survey instrument


Hardware


2 version available

2 wheels 4 wheels

Hardware

• Dual Frequency Antenna in Pivoting Head

• GPS

• 2 Wheel encoders

Opera Duo HW Features


Dual Frequency antenna 250 & 700 MHz

Adjustable handle gives you the perfect grip

Pivoting head

Large wheels gives stability and let the system do not sink

Collapsible handle

Hardware features All the parts are integrated in the main body of the products including a dual frequency 250-700 MHz antenna, a 400 KHz control unit, a battery and two encoders.


Encoders battery

Dual frequency antenna and control unit

Pivoting head


The head of the Opera Duo can rotate along a longitudinal axis in order to let the antenna be always in contact with the ground in any soil condition.

Accessories

Spray marker kit:

Remote controlled spray paint marker kit to mark utilities and targets with the minimum effort.

A button in the interface regulate the spray.

The kit can be mount in 10 seconds.


Accessories

GPS mounting kit:

Aluminum kit to hold a GPS pole. Connection with the PC is available through bluetooth or Serial ports.



Acquisition Software

• Smart graphic layout optimized for touchscreens

• Real time estimation of propagation velocity

• Advanced troubleshooting

• Advanced Positioning management

• Digital map exportation

• Report done on site


Opera Duo SW Features

Map Panel

Map importation and GPS for positioning management

The user can import map in several format, or if connected with the internet, can download in real time the map of the area.

If GPS is used the navigation interface will show the current position of the radar, the path trajectory and the targets inserted.


Google map importantion through internet

“New project” acquisition


MAP Radargram

troubleshooting

Few seconds are necessary to acquire data with New Project modality.

A map will help the user geo-locating the acquisition.

“New assisted Project” acquisition


A guided tool will help the user to design and collect data along a grid.

Professional survey made easy with the assisted modality!


Guided grid acquisition


Opera Duo SW report output

Every project can be exported as a report.

The report include major information including an overall map of the area, the targets detected with their coordinates, a general description of GPR etc.


Opera Duo SW CAD output

Export to DWG for importing into your GIS or CAD solution

Why GPR?

• GPR technology can locate any pipes / structures / objects: metallic and non-metallic (PVC, concrete, etc.)

• GPR is non-destructive and non-invasive, revealing a wealth of internal detail without the need for coring or breaking out reducing associated risks and costs;

• GPR complements the surface inspection with a documentable and precise (quantitatively interpretable) image of the underground.
