For decades, RADAN has been at the heart of GPR post-processing for thousands of professionals worldwide. However, as the GPR industry evolves toward cloud-based, collaborative workflows, GSSI is focused on software development efforts in partnership with Geolitix to provide seamless integration for our customers.
Therefore, effective September 29, 2026, RADAN will no longer be available for standalone purchase, and active development of the software has ceased. Your existing license(s) will remain functional, but there will be no new features, modules, or updates to RADAN going forward.
This is not a decision made lightly. RADAN is one of GSSI’s most enduring products, and we have enormous respect for the community of professionals like you who have made it the industry standard. But as the technology landscape evolves, and as our customers’ needs shift toward faster, more collaborative, and more accessible workflows, we believe the time is right to focus on what’s ahead.
YOUR RADAN LICENSE IS SAFE
RADAN is a perpetual license; it's yours and will continue to function exactly as it does today. The software is not being disabled. You can continue to use RADAN as you always have.
LIMITED SUPPORT CONTINUES
After September 29, 2026, GSSI will continue to support the management of your existing license seats, including deactivations, reactivations, transfers between machines, and critical stability issues. Existing training videos and documentation remain available.
SITE LICENSE CUSTOMERS
If you have a RADAN site license and may need additional seats, please purchase additional activations before September 29, 2026. After this date, no new site license activations will be sold, although existing seats can still be deactivated, reactivated, and transferred.
RADAN 6 USERS
If you’re running RADAN 6 and want to upgrade to RADAN 7, we recommend Geolitix as the better long-term option. If you prefer to upgrade to RADAN 7, please complete that purchase before September 29, 2026. After this date, RADAN 6 to RADAN 7 upgrades will end.
ROADSCAN & BRIDGESCAN UNAFFECTED
RADAN will continue to ship as a bundled component with both RoadScan™ and BridgeScan™ hardware. RoadScan hardware sales will now automatically include the RADAN RoadScan Module, just like BridgeScan. Your workflow does not change.
THE PATH FORWARD
We encourage all users who need powerful post-processing capabilities to explore Geolitix, which is available at a discount directly through GSSI. GSSI provides full-service support and training on the Geolitix platform.
Why Now?
The GPR industry is changing. Projects are getting larger. Teams are more distributed. Clients expect faster turnarounds and more visual, shareable deliverables. The desktop-only, single-user model that served us well for decades is giving way to cloud-based platforms that can handle massive datasets, automate complex processing, and enable real-time collaboration from anywhere.
That’s why, last year, we announced our strategic partnership with Geolitix, a modern, cloud-based GPR processing platform that represents the future of how professionals will work with subsurface data.

No. RADAN is a perpetual license — it’s yours and will continue to function. We are ending new standalone sales and active development, not disabling your software.
Only until September 29, 2026. After this date, no new site license activations will be sold. However, your existing seats remain fully manageable — you can deactivate a seat on one machine and reactivate it on another, or transfer seats as needed. If you anticipate needing more seats, please complete those purchases before September 29, 2026.
Only until September 29, 2026. After this date, GSSI will no longer sell RADAN 6 to RADAN 7 upgrades. If you want to upgrade, please complete the purchase before the deadline. We also encourage you to evaluate Geolitix as a modern alternative. You can reach out to us for a free 3-month trial that gives you a no-risk way to compare the two before making a final decision.
Yes, limited support will continue. This includes management of your existing license seats (deactivations, reactivations, transfers between machines) and critical stability fixes at GSSI’s discretion. Feature requests, new module development, new seat sales, RADAN 6 to 7 upgrades, and OS compatibility work will not be supported.
No. RADAN will continue to be bundled with both RoadScan and BridgeScan hardware purchases. Going forward, RoadScan hardware will automatically include the RADAN RoadScan Module — matching how BridgeScan has always worked. Your workflow does not change, and both bundled modules will continue to receive full technical support.
No, an upgrade path is not available because the licensing models are different. RADAN is sold as a perpetual subscription, which you own and can use forever. It is not a subscription that can be converted or upgraded to Geolitix.
Yes, absolutely. Geolitix is designed to be compatible with data from a wide range of GPR systems, including legacy GSSI equipment like the SIR 3000, SIR 20, and legacy concrete scanners. You can easily transfer the DZT files from your control unit to a computer and then upload them directly to the Geolitix platform for processing.
Our strategic partnership allows us to offer you an exclusive discount on 2-year subscriptions for any Geolitix package. This extended term provides significant savings compared to the standard monthly or annual subscriptions that are available when purchasing directly from Geolitix, giving you the best value for your investment.
