GSSI Announces David Cist as New VP of R&D

GSSI, the world’s leading manufacturer of ground penetrating radar (GPR) equipment, is pleased to announce the promotion of David Cist to the position of Vice President of Research & Development. An exceptional leader and innovator, since 1996, Dr. Cist has helped GSSI to develop several key products, including an arrayed utility mapper and a series of search and rescue tools.

Promoted from “Chief Geek” in 2015, and more recently to interim Director of R&D, Dr. Cist continues to provide the leadership GSSI needs to drive innovation and product strategy forward.

According to GSSI President, Chris Hawekotte, “I am pleased to announce the promotion of David Cist to the position of VP of Research & Development. David has led the organization in this capacity on an interim basis since last September and has convinced us that he is right to take on this role permanently. I am confident that he will continue to extend GSSI’s lead as the technological front-runner in GPR.”

A long-time GSSI employee, Dr. Cist recently celebrated his 21st year with the organization, having served in prior roles as Senior Software Engineer and also as Manager of Product Strategy and Planning. After graduating from Princeton University with a BSE degree in Electrical Engineering and Computer Science, Dr. Cist worked in market research and then in R&D for Siemens Medical in Germany. There he developed the first ever voice recognition tool for cardiac catheterization procedures. Dr. Cist completed his education at Massachusetts Institute of Technology, with a Master’s degree in Radiology Science (Simulated Annealing image reconstruction), and finally a PhD in Geophysics (3D Migration of GPR data).

GSSI is confident Dr. Cist’s new position as technical lead will foster innovative solutions that further extend GSSI’s flagship role in the GPR industry.


GSSI Announces a New UtilityScan® GPR System for Quickly Identifying and Marking Utility Location and Depth

Nashua, NH - GSSI announces a new UtilityScan GPR system, adding an affordable model to the industry standard system for efficiently identifying and marking the location and depth of subsurface utilities. The new UtilityScan features innovative technology never before available in the marketplace. The compact size makes it extremely portable and easy to maneuver in tight survey areas. This model is designed specifically to meet the needs of electrical contractors, utility installers, and municipal and state gas and water utilities. The UtilityScan sets a new standard in performance and price.

UtilityScan features a robust new wireless antenna that can handle required data rates and is ruggedly built to withstand challenging field conditions.  The electrical design uses GSSI’s patented HyperStacking technology, which has proven to increase depth penetration in challenging soils, while also providing high near surface data resolution. The unit also has a backup Ethernet connection if Wi-Fi is not desired or allowed on a particular jobsite or facility.

The UtilityScan can also be equipped with the new LineTrac™ accessory, which helps locate specific power sources situated underground, including AC power and induced RF energy present in conduits. Coils that detect power radiated from electrical cables are combined with GSSI’s next generation GPR radar into a single box. The accessory lets users produce an overlay on the radar data that represents the presence of AC power and/or induced RF energy present in conduits – invaluable for this application.

All new UtilityScan system from GSSI

The new model uses a wireless tablet-based system and a simplified app-based user interface that is convenient and easy to use. The tablets feature a built-in GPS, which can be used for providing location information in the radar data file. Two tablet options are available, including the fully-rugged Panasonic® Toughpad FZ-B2 and the consumer-based NVIDIA SHIELD tablet.

The UtilityScan is the smallest utility locating GPR system on the market. Weighing in at only 34 pounds, the UtilityScan when folded is 22-inches by 19.25-inches by 12.5-inches and can fit in the back of a small vehicle or in some overhead airplane compartments. The case design is manufactured using a structural foam injection molding process, which results in parts that are very light, but strong and extremely rugged. The basic cart configuration is designed for use on prepared surfaces, including concrete; asphalt, or compacted dirt. A cart upgrade is available for use on grassy areas, unpaved trails and wooded areas.

The system design accommodates existing GPS systems used for surveying applications. The UtilityScan system has a built-in GPS pole mount for attaching survey poles with external GPS systems and software that can communicate with the GPS systems via Bluetooth.

GSSI’s New PaveScan® RDM Asphalt Assessment Tool Ensures Pavement Life and Quality

Nashua, NH - GSSI, the world’s leading manufacturer of ground penetrating radar (GPR) equipment, announces its new PaveScan® RDM asphalt assessment tool, which provides accurate real-time measurements to ensure pavement life and quality. First unveiled at the 2016 Transportation Research Board (TRB) Annual Meeting, PaveScan is already generating excitement and interest among those seeking an easy and affordable assessment tool to nondestructively determine asphalt integrity during application.

The PaveScan RDM system is ideal for uncovering problems that occur during the paving process, including poor uniformity and significant variations in density. By avoiding these problems, PaveScan RDM helps avoid such premature failures as road raveling, cracking, and deterioration along joints.

PaveScan automatically measures the dielectric value to identify anomalies in real-time. In addition, the dielectric values can be used to as a means to correlate percent voids and density in new pavement. The innovative technology enables users to obtain critical density data for QA/QC of new pavements. Unlike other options like nuclear density gauges or radioactive alternatives, PaveScan does not result in any site hazards or require closing off work areas.

Seamlessly integrating with GPS systems, PaveScan features a flexible, modular design that facilitates easy and efficient operation and data collection. It is available as a small, portable single sensor cart-based system or a three-sensor configuration using an extended cart or vehicle configuration. The entire system is composed of a cart or vehicle mount, one to three sensors, a customized Panasonic ToughBook, a concentrator box and a variety of system accessories.

Title: Testing Bridges Under the Stars

Submitted by: Infrasense, Inc.
Woburn, Massachusetts USA

This shot was taken in Idaho, just along the state border with Montana. Infrasense was performing bridge deck condition surveys and pavement thickness surveys on Interstate 15 using a vehicle-mounted dual 1GHz horn antenna setup and
SIR 20 from GSSI. We decided to take a break from our work and snap some photos of the impressive Milky Way - one luxury of working out in these sparsely populated areas is the opportunity to do some real star gazing! It was so dark out, we had to use our cellphone flashlights to illuminate the vehicle so that it would appear in detail for my photo. This photo was shot on a Canon 6D with a Sigma 20mm F/1.4 lens
