SAL SPU-200 Ready for Jammertest 2025

SAL Navigation is preparing for the next round of full-scale jamming tests at Andøya, Norway – the world’s largest open testbed for GNSS interference. This unique event provides a controlled environment where jamming and spoofing can be carried out safely and realistically, offering the maritime industry unparalleled insight into system behavior under real-world conditions.

Industry-Leading GNSS Resilience Testing – Technology Built on Real-World Conditions

For years, SAL Navigation has worked at the forefront of addressing GNSS vulnerabilities — not only through product development, but by shaping how the maritime industry approaches testing, verification, and operational validation under real-world GNSS interference and spoofing scenarios.

Together with Norwegian partners, SAL Navigation played a key role in identifying the need and pushing for a large-scale GNSS jamming testbed. Initiated in 2021 under the direction of Norwegian authorities along with national defense and research institutions, the testbed at Andøya, Norway was established the following year.

Operational Consequences and Competitive Advantage

• Real signal, real interference: GNSS spoofing and jamming cannot be meaningfully tested using only simulators or lab environments. Authentic GNSS signals must be disrupted by real jammers in controlled outdoor conditions to assess true system behavior.
• Unique test environment: Jammertest at Andøya provides one of the only controlled areas in the world where full-scale GNSS jamming is legally and safely conducted for non-military entities. Its remote location and open geography make it ideal for wide-area, high-fidelity testing.
• Raising the industry standard: SAL Navigation has led the way in defining how GNSS resilience should be tested — pushing beyond simulations to realistic scenarios involving operational systems and infrastructure.
• Independent validation: SAL SPU-200 is not just tested in these environments — it is part of the effort that made such testing possible. This foundation gives unique credibility to its real-world performance claims.
• Cross-sector adoption: Due to the proven value of this approach, the test program has been extended to cover multiple transport sectors, including maritime and road transport, becoming a benchmark for GNSS reliability.

Any solution designed to protect against GNSS interference must be validated in a real jamming environment. SAL SPU-200 has been tested under such conditions and has demonstrated consistent and reliable performance. In addition, extensive field trials in the Baltic Sea — one of the most affected regions in recent months — have further confirmed its operational resilience.
