VIAVI Bolsters Assured PNT Portfolio with LEO-Aided Navigation System
Event summary
- VIAVI Solutions’ Inertial Labs division launched the IRINS LEO-aided inertial navigation system on January 29, 2026.
- IRINS integrates an INS, AHRS, and Iridium’s STL-2600 LEO receiver to provide positioning, navigation, and timing (PNT) capabilities in denied/degraded environments.
- The system is designed to counter spoofing and jamming attacks targeting military and critical infrastructure.
- IRINS is certified for IP67 and MIL-STD-810G environmental requirements and housed in a compact enclosure (126.5 × 49.3 × 53.3 mm).
The big picture
The launch of IRINS underscores the growing importance of assured PNT in an era of increasing geopolitical instability and sophisticated cyberattacks. VIAVI’s strategic integration of Inertial Labs’ INS expertise with Iridium’s LEO capabilities addresses a critical need for resilient navigation solutions, particularly for sectors reliant on GNSS signals. This move positions VIAVI to capitalize on the expanding market for anti-jamming and resilient navigation technologies, which is expected to see significant growth as vulnerabilities in existing systems become more apparent.
What we're watching
- Government Contracts
- The success of IRINS will hinge on securing government contracts, particularly given the stated focus on military and critical infrastructure applications; competition for these contracts is intense.
- Iridium Dependency
- VIAVI's reliance on Iridium’s LEO constellation creates a potential single point of failure and could limit scalability if Iridium capacity or pricing changes.
- Competitive Landscape
- The emergence of other LEO-aided navigation solutions will likely intensify, requiring VIAVI to continually innovate and differentiate IRINS to maintain market share.
