Viavi Solutions announced a partnership with satellite‑communications provider Ground Control to integrate its Secure µPNT STL‑1000 receiver into Ground Control’s RockFLEET Assured asset‑tracking platform. The integration will give maritime vessels a reliable secondary position source that can operate when GPS/GNSS signals are jammed, spoofed, or otherwise unavailable, thereby enhancing resilience in denied, degraded, and disrupted space operational environments (D3SOE).
The Secure µPNT STL‑1000 is a compact, software‑defined receiver that works with Viavi’s SecureTime altGNSS LEO services. Together they provide encrypted, secure positioning and timing signals that are up to 1,000 times stronger than conventional GNSS, offering a robust backup for ships operating in contested maritime corridors.
Viavi’s expansion into the maritime PNT market is driven by the growing threat of GPS/GNSS jamming and spoofing, which have been reported in key trade routes such as the Baltic, Black Seas, Arabian Gulf, and Straits of Hormuz. By adding this capability, Viavi positions itself to serve defense, autonomous vessels, coastal surveillance, and critical infrastructure protection—sectors that demand assured navigation in hostile environments.
The partnership places Viavi alongside other maritime PNT players, giving it a competitive edge by combining its secure, high‑strength signals with Ground Control’s proven shipborne platform. This alignment strengthens Viavi’s market position and opens new revenue opportunities in a sector that is increasingly reliant on resilient navigation solutions.
Doug Russell, Senior Vice President and General Manager of Aerospace and Defense at Viavi, said, “With jamming and spoofing now a core element of cyber warfare, resilient PNT solutions are no longer optional.” Alastair MacLeod, CEO of Ground Control, added, “Integrating VIAVI’s Secure µPNT STL‑1000 into RockFLEET Assured delivers a trusted secondary position source, strengthening resilience for mission‑critical operations across defense, maritime and critical infrastructure environments.”
The partnership is part of Viavi’s broader strategy to expand into high‑growth technology sectors, including AI data‑center infrastructure, cybersecurity, and autonomous systems. By extending its resilient PNT portfolio into the maritime domain, Viavi is positioning itself to capture a share of the growing demand for assured navigation in contested environments, reinforcing its role as a key technology partner for defense and critical‑infrastructure customers.
