Key Terms

2 terms

gnss technical

"navigation in GNSS-denied environments."

GNSS stands for Global Navigation Satellite System, a network of satellites that provide precise location and timing information anywhere on Earth, like a constantly available digital map and clock. It matters to investors because many industries—transportation, agriculture, telecom, finance and defense—rely on this positioning and timing for products, services and critical infrastructure; improvements or disruptions in GNSS can change costs, create new revenue streams, or introduce operational risk.

altgnss technical

"operate with the VIAVI SecureTimeSM altGNSS LEO services."

Alternative GNSS refers to satellite-based navigation systems other than a single dominant system (for example, networks that provide positioning, timing and navigation alongside or instead of GPS). Like having multiple clocks or maps to find your way, these alternative systems reduce reliance on one provider, lower geopolitical and technical risk, and can create new markets for chips, receivers and services—factors investors watch for technology, defense and infrastructure opportunities.

Secure µPNT STL-1000 provides precise timing with holdover capability in D3SOE

CHANDLER, Ariz., April 2, 2026 /PRNewswire/ -- VIAVI Solutions Inc. (VIAVI) (NASDAQ: VIAV) today announced its partnership with satellite communications and positioning solutions provider Ground Control to integrate its Secure µPNT™ STL-1000 into the RockFLEET Assured asset tracking and assured navigation solution.

In today's contested global environment, resilient Position, Navigation and Timing (PNT) capabilities are crucial to safeguard critical infrastructure and assets. Reliance on GPS/GNSS alone leaves systems vulnerable to jamming, spoofing and disruption. VIAVI's Secure µPNT STL-1000 is a compact software-defined receiver designed to operate with the VIAVI SecureTime^SM altGNSS LEO services. Delivering precise timing with holdover capability, it enables tracking, authentication and assured navigation in Denied, Degraded, and Disrupted Space Operational Environment (D3SOE).

"With jamming and spoofing now a core element of cyber warfare, resilient PNT solutions are no longer optional," said Doug Russell, Senior Vice President and General Manager, Aerospace and Defense, VIAVI. "The Secure µPNT STL-1000 enables assured, uninterrupted operations, especially in contested environments. Its compact size and low power consumption makes it ideal for applications that require an extremely small, low-power, secure, resilient embedded PNT receiver."

"As the frequency of jamming and spoofing continues to rise, reliance on GPS/GNSS signals alone increasingly exposes both commercial and military operations to risk," said Alastair MacLeod, CEO of Ground Control. "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."

RockFLEET Assured is a marine-grade Assured Position, Navigation and Timing (A-PNT) solution designed to support maritime vessel navigation and oversight in GNSS-denied environments.
