VIAVI, Ground Control Partner to Enable Assured Maritime Vessel Tracking and Navigation

Key Takeaways

• VIAVI partners with Ground Control to embed Secure µPNT STL‑1000.
• Secure µPNT provides resilient PNT in jammed, spoofed environments.
• Integration adds trusted secondary positioning to RockFLEET Assured.
• Solution targets defense, maritime, and critical infrastructure sectors.
• Compact, low‑power receiver supports embedded applications on vessels.

Summary

VIAVI Solutions has teamed with satellite‑communications specialist Ground Control to embed its Secure µPNT STL‑1000 receiver into the RockFLEET Assured maritime tracking platform. The compact, software‑defined device works with VIAVI’s SecureTime altGNSS LEO service to deliver precise timing and positioning even when GPS signals are jammed or spoofed. By providing a trusted secondary PNT source, the integration aims to safeguard vessel navigation in denied, degraded, and disrupted space environments. The solution targets defense, commercial shipping, and critical‑infrastructure operators facing growing electronic‑warfare threats.

Pulse Analysis

In today’s contested maritime domain, reliance on traditional GPS is increasingly risky. Adversaries can jam or spoof satellite signals, creating blind spots for vessels that depend on precise timing and location data. This vulnerability not only threatens commercial shipping routes but also compromises military logistics and critical infrastructure monitoring. As global tensions rise, the industry is seeking alternative positioning methods that can operate independently of vulnerable GNSS constellations, prompting a surge in demand for resilient, multi‑layered PNT solutions.

VIAVI’s Secure µPNT STL‑1000 addresses these challenges with a software‑defined architecture that leverages altGNSS low‑Earth‑orbit (LEO) services from its SecureTime platform. The receiver’s hold‑over capability maintains timing accuracy during signal loss, while its authentication mechanisms verify data integrity, protecting against spoofing attacks. Its compact form factor and low power draw make it ideal for integration into existing vessel systems, allowing operators to augment legacy GPS with a trusted secondary source without extensive hardware overhauls. Ground Control’s expertise in satellite communications further enhances coverage, ensuring continuous positioning even in remote or heavily contested waters.

The partnership’s impact extends beyond immediate operational resilience. By delivering assured navigation to defense fleets, commercial carriers, and offshore infrastructure, the solution supports broader strategic objectives such as supply‑chain continuity and maritime domain awareness. As cyber‑warfare tactics evolve, the market for secure, dual‑mode PNT technologies is poised for rapid growth, encouraging further innovation in LEO constellations and edge‑computing integration. Stakeholders that adopt these capabilities now will gain a competitive edge, mitigating risk while meeting regulatory expectations for safety and reliability.
