The increasing threat of GNSS signal jamming and spoofing poses serious risks to global maritime navigation, with potentially severe consequences for vessel safety. In response to this growing challenge, SAL Navigation has developed and launched SAL SPU-200—an advanced precision system that sets a new benchmark in maritime security technology. Rigorously tested in real-world conditions, the system has demonstrated unmatched resilience against jamming and spoofing attacks, with test results confirming its superior performance over traditional SOLAS-class GPS/GNSS systems.
Over the past decade, deliberate interference with GNSS signals has intensified, disrupting navigation systems and increasing risks for vessels worldwide. As maritime operations become more reliant on satellite-based positioning, the need for robust anti-jamming and anti-spoofing solutions has never been more critical. SAL SPU-200 is engineered to meet these challenges, ensuring uninterrupted navigation data even in the most extreme interference environments.
SAL SPU-200 has undergone extensive testing at Andøya, Norway—home to the world’s largest open PNT/GNSS resilience trials. These large-scale trials, conducted under high-power jamming and spoofing scenarios, have confirmed the system’s superior performance compared to traditional SOLAS-class navigation systems. Researchers from the Norwegian Coastal Authorities vetted the trials, validating SAL SPU-200’s ability to maintain reliable, uninterrupted position data even in extreme jamming environments.
SAL SPU-200 demonstrates superior resilience, maintaining robust satellite tracking and delivering reliable data even under extreme jamming conditions. With interference suppression levels of 20 dB using a standard antenna and up to 50 dB with an advanced CRPA antenna, it provides unmatched performance in demanding environments, ensuring resilience under conditions typical of regions with geopolitical tensions.
Engineered to withstand military-grade jamming, SAL SPU-200 delivers unmatched protection against GNSS interference, ensuring vessels maintain access to secure positioning data even when primary navigation systems are compromised. In high-risk waters and geopolitically sensitive regions, it acts as a critical safeguard, enabling continued safe and reliable navigation.
With the launch of SAL SPU-200, SAL Navigation strengthens its position as a leader in maritime navigation technology. By integrating cutting-edge anti-jamming and anti-spoofing capabilities with rigorous real-world testing, SAL Navigation delivers a system that is essential for ensuring modern maritime security.
