US Radar GP Rover Combines Advanced Subsurface Radar and Global GPS For Highly Accurate Underground Mapping

Mobile system meets needs of contractors, engineers, utilities, public works and others

MORGANVILLE, N.J. – January 24, 2018

US Radar Inc., the leading innovator of ground penetrating radar (GPR) and subsurface imaging systems, today introduced the GP Rover™, which combines US Radar’s advanced triple-bandwidth ground-penetrating radar technology with precision global GPS connectivity to create subsurface maps in real time, with no base station or control points required and accurate within two inches (5 cm) “out of the box.”

“Maps created using the GP Rover provide a permanent and updateable record that can be shared by all contributors to a project,” said Ron LaBarca, president of US Radar. “The GP Rover overcomes the limitations of impermanent ‘mark-outs’ that often lead to costly errors in subsequent excavations.”

LaBarca also noted that newly patented tilt-correction technology on the GP Rover automatically compensates for slope and cross-slope of the GPR and GPS antennas to increase overall accuracy on uneven terrain.

Field data collected by the GP Rover may be saved and shared in any of the five most common file formats – SHP, DXF, KMZ, CSV, RTF – used in popular mapping and engineering applications such as AutoCad, Google Earth, GIS and point files.

Total integration of advanced GPR and GPS technologies

“The information and maps the GP Rover generates will be valuable to users across a variety of industries,” LaBarca said. “With its combination of accuracy and ease of use for locating and mapping, the GP Rover is poised to become the new measure of excellence in ground-penetrating radar systems.”

Among the potential users are contractors, engineers, utility-locating service providers, public works organizations, utility companies, municipalities, planners, architects, surveyors, property owners, oil fields, ports and inspectors.

“The GP Rover combines high accuracy and differential GPR locating capabilities with the most accurate and responsive GPS location-positioning software in an easy-to-learn, easy-to-use operator interface,” LaBarca said.

Usable worldwide with no extra subscriptions required. He noted that one of the key benefits is that the GP Rover can be used effectively anywhere in the world. “Users won’t have to subscribe to another service when they cross county or state lines, regions or even cross international borders,” he said. This is possible because the GP Rover connects with the global Starfire GPS network – a service of John Deere subsidiary NAVCOM. This enables the new US Radar system to provide full GNSS (Global Navigation Satellite System) reception and automatically receive corrections from INMARSATs (International Maritime and Marine Satellites).

The GP Rover does not require complicated setup and network configuration, LaBarca explained. It automatically connects to the worldwide GPS network and configures as soon as the radar is turned on. “With the GP Rover, any operator can create an accurate point file, preserve location points without destructive surface markings, display location points on the integrated computer screen, export points to mapping applications and view in real-time locations on as-built maps,” he said.

New, top-of-the-line system saves costs

“The GP Rover eliminates the need for GPS correction services,” he continued, “by delivering an integrated solution for subsurface mapping that combines the best GPS network connectivity, the most powerful GPR technology, built-in mapping software and fully integrated electronics with an easy-to-use interface.”

An exclusive “field-to-finish” capability in US Radar’s software program – Radar Studio – saves time and eliminates possible confusion and error by automatically mapping coordinate points that are identified with the same name; e.g., “Gas Line 1.”

The GP Rover uses the same battery for both GPR and GPS systems, eliminating the need for costly additional batteries. US Radar has engineered and integrated sophisticated electronics into the GP Rover’s waterproof and dustproof antenna. This rugged system qualifies for an IP65 weatherproof rating.

Harnesses US Radar’s triple-frequency technology

The GP Rover uses US Radar’s innovative triple-frequency radar technology for locating and imaging objects at greater depths and with higher resolution than competitive single- or dual-frequency systems. This proven technology was introduced in 2014 with US Radar’s Quantum Imager GPR system.

Triple-frequency radar offers superior imaging in a wide variety of applications, from analysis to locating and imaging utilities at depths up to 30 feet – twice the depth limit of dual-frequency systems and three times that of single-frequency units. Ultra-wideband pulses combine the advantages of pulse radar and stepped-frequency radar. The system is especially effective in locating objects such as conduit and rebar, and rendering high-resolution imagery of those objects. Direct radio frequency sampling technology creates clearer, easier-to-understand images than previously possible with older radar technologies.
