Topcon Expands Geospatial Portfolio Through GSSI Integration
Topcon Positioning Systems and Geophysical Survey Systems, Inc,have announced a strategic collaboration designed to bring together advanced ground penetrating radar (GPR) technology with high-precision global navigation satellite system (GNSS) positioning and cloud-based data management. The integrated solution is aimed at transforming how infrastructure and construction professionals capture, interpret, and act on subsurface and spatial data across a wide range of projects.
The partnership unites GSSI’s industry-leading ground penetrating radar systems with Topcon’s advanced positioning hardware and digital workflow tools. By combining GPR data with accurate GNSS coordinates and streamlined processing software, the companies are delivering a seamless solution that connects underground intelligence with above-ground spatial context. The result is a more comprehensive and decision-ready view of job sites, helping professionals reduce risk, improve productivity, and enhance project outcomes.
Ground penetrating radar has long been a critical tool for detecting and mapping subsurface features such as utilities, voids, rebar, conduits, and other buried infrastructure. GSSI has built a reputation as a pioneer and global leader in GPR technology, serving industries ranging from construction and engineering to transportation and environmental assessment. Its systems are widely recognized for their reliability, precision, and ability to generate high-resolution subsurface images.
Through this collaboration, GSSI’s GPR systems will be integrated with Topcon’s HiPer XR GNSS receiver, enabling highly accurate geolocation of subsurface findings. The HiPer XR receiver is designed to deliver robust, multi-constellation satellite tracking and reliable performance in challenging environments. By tagging radar data with precise positioning information, field teams can more accurately map underground assets and conditions relative to surface features and project plans.
In addition to hardware integration, the solution incorporates Topnet Live correction services, which provide real-time GNSS corrections to enhance positioning accuracy. This ensures that data collected in the field meets the high precision requirements of infrastructure and construction applications, where even small discrepancies can lead to costly delays or rework. Real-time corrections help streamline field operations and reduce the need for repeat surveys.
The integrated workflow is further supported by Collage Web mass-data workflow software. Collage Web enables teams to upload, process, visualize, and analyze large datasets collected from both GPR and GNSS systems. By centralizing data management in a cloud-enabled environment, the platform allows project stakeholders to collaborate more effectively, review findings in near real time, and make informed decisions based on a unified dataset.
Ron Oberlander, head of the Topcon Geomatics Platform, emphasized the value of the collaboration in bridging the gap between subsurface detection and spatial analysis. He noted that GSSI’s long-standing leadership in GPR technology makes the company an ideal partner for delivering an advanced, integrated solution to industry professionals. By combining GSSI’s radar capabilities with Topcon’s positioning technology and digital workflow tools, the companies are enabling a connected workflow that spans from field data capture to office-based analysis.
The ability to link underground intelligence with accurate spatial positioning addresses a critical need in infrastructure and construction projects. Whether teams are preparing for excavation, conducting utility mapping, assessing pavement conditions, or verifying as-built documentation, having reliable subsurface data aligned with precise geolocation reduces uncertainty. This integration supports better planning, faster validation of findings, and improved communication among project stakeholders.
Chris Green, chief executive officer of GSSI, highlighted the importance of unifying GPR and GNSS data to deliver visual, decision-ready insights. He explained that by bringing together complementary technologies, the partnership provides customers with a more complete picture of the world both above and below the surface. This comprehensive perspective helps teams identify potential conflicts early, avoid unexpected obstacles during construction, and maintain higher standards of quality and safety.
In practical terms, the integrated solution can help contractors and engineers detect buried utilities before breaking ground, minimizing the risk of accidental strikes that can cause project delays, service disruptions, and safety hazards. For transportation agencies, the combination of radar and positioning data can support pavement assessments and maintenance planning. For utility owners and surveyors, the solution offers improved documentation of underground assets, enhancing long-term asset management.
The collaboration reflects a broader industry shift toward digitalization and data-driven decision-making in construction and infrastructure development. As projects grow in complexity and stakeholders demand greater efficiency and accountability, the integration of complementary technologies becomes increasingly important. By connecting subsurface sensing with high-accuracy positioning and cloud-based workflows, Topcon and GSSI are helping to modernize traditional surveying and inspection practices.
The new solution will be showcased at CONEXPO-CON/AGG, North America’s largest construction trade show, taking place March 3–7 in Las Vegas. Attendees will have the opportunity to see demonstrations of the integrated system at both the Topcon Positioning Systems booth and the GSSI booth. The event provides a platform for industry professionals to explore how the combined technologies can enhance efficiency, accuracy, and confidence in the field.
By aligning advanced ground penetrating radar with precise GNSS positioning and scalable data management, Topcon and GSSI are delivering a powerful new toolset for infrastructure and construction professionals. The collaboration underscores a shared commitment to innovation and to providing customers with solutions that reduce risk, increase productivity, and enable smarter, more informed decision-making across the project lifecycle.
