PinPointR
from ImpulseRadar
A compact and robust high frequency GPR system which has been specifically designed to meet the requirements of the utility detection industry. The PinPointR GPR system combines Impulse Radar’s real-time sampling (RTS) technology with a dual set of antenna to provide unquestionable data fidelity and resolution.
As a Dual frequency system, the PinpointR (Fig.1) allows the user to collect simultaneous data at two depth ranges using the 400MHz and 800MHz antenna and targets picked from either channel on the fly. Under good ground conditions (well drained sandy loam soil) the user can image around 2m and 5m below the ground surface and pick up on structures and features such as electric, water mains, gas pipes and other common utilities found within this depth range. The system can help the user detect, locate and track one or more features beneath the surface and plot the results up on a map; swaths can be collected in an X,Y grid format or as single lines. As with all GPR systems it is difficult to distinguish the type of utility being detected, therefore the system must aid other information (e.g. previous known data/ estimated depth of a utility) gathered from the area to help interpret the data.
The compact all-in-one design means the systems can be stored and transported complete so that it is ready for use at a moments notice. It can easily pack in the boot of your car a relatively lightweight system with a handle which folds out ready for you to start acquisition. Powered using a single Li Ion battery the system communicates via WIFI to any android device (Phone, tablet) which has the Viewpoint acquision software installed (Freely available). The operator then can choose between single acquisition or multi line acquisition mode (Fig2.) and choose the depth window and set to internal or external GPS mode. If a more accurate position is required (e.g. RTK FIX 4) , any RTK system running a GGA NEMA sentence can communicate with the PinpointR.
The data exported can be interpreted and processed in GPR-Slice or the Crosspoint software before being exported in a CAD readable format.
The dual channel electronics permit both frequency antenna to be recorded simultaneously and targets picked from either channel on the fly. The compact all-in-one design means the systems can be stored and transported complete so that it is ready for use at a moments notice.

Application Notes
Data Enhancement Tools
ViewPoint data aquitions software is easy to use with interactive data processing tools to assist enhance anomalies for interoperation on the fly.
Georeferencing on the Fly
ViewPoint permits operators to pull in aerial imagery and view marked features on the fly. When leaving a project the user will be prompted to generate a PDF Field Summary report and a KMZ files.
Local Grid Project
The RL-project associates and orientates GPR profiles to a straight-line reference. This reference line can be any type of physical line visible within the survey area during and after data collection. Examples include boundaries, curb lines, fence lines, or merely a metering-tape laid on the ground. Regardless, one end of the line needs to be defined as the starting point and then equidistant points marked along its length. Profiles are gathered in straight lines, perpendicular to the reference line, and a reference-marker is placed within the GPR data every time the reference line is crossed.
FAQ's
How do I download my ImpulseRadar Viewpoint files from my Android device?
In August 2022, Android released version 13 of their operating system. New data security measures restrict access to folders/files apps can open from the device memory, this includes the file explorer app supplied with the Android installation. Single Line and Multi Line Project folders can exported through the VeiwPoint application.
1) Open the ViewPoint App 2) Press the [Folder] icon 3) Navigate to the Single or Multi line project folder to be downloaded 4) Press and hold on the project folder until the sub menu opens with the options Send, Zip and Delete. 5) Zip the project folder 6) Press and hold on the Zipped project folder until the sub menu opens. 7) Press [Send] 8) Choose the path you want to send the Zipped folder to. this could be an Expernal USD memory drive or cloud storage.
