GPS Jamming & Spoofing Threaten Maritime Navigation
Maritime sector faces vulnerabilities from GPS jamming and spoofing, threatening global trade and safety. AST Networks warns vessels must seek advanced countermeasures.

The Growing Threat of GPS Jamming and Spoofing
GPS jamming occurs when a device deliberately transmits signals on the same frequencies used by GPS satellites, effectively drowning out legitimate signals and rendering GPS receivers useless. Spoofing, on the other hand, is a more insidious threat involving transmitting false GPS signals to deceive receivers into believing they are at incorrect locations. Both tactics can severely disrupt maritime operations leading to navigational errors, collisions, or even vessels straying into restricted or dangerous waters.
Recent reports highlight how Russian-origin jamming has disrupted GPS signals across European airspace, forcing aircraft to re-route and, in some cases, cancel flights. Whilst much attention has been given to the aviation industry, AST Networks emphasises that maritime operations are equally exposed. In high-risk regions, including the Baltic Sea and the Eastern Mediterranean, vessels navigating without back-up solutions are at heightened risk of being misled or rendered positionally blind. The consequences of this interference are far-reaching, affecting commercial shipping, fishing operations, offshore energy installations, and even search and rescue missions.
“GPS interference is no longer just a theoretical risk; it is an active threat to global navigation and security,” said Lukasz Latosinski, GNSS expert at AST Networks. “Jamming and spoofing attacks can deceive ships into believing they are on a safe course when in reality, they may be heading into hazardous waters or restricted areas. This puts cargo, crews, and even national security at stake.”
A Proven Solution: The SAL SPU-200
AST Networks is an approved reseller of the SAL SPU-200, an advanced anti-jamming and anti-spoofing unit developed by SAL Navigation to safeguard maritime navigation. The system integrates multi-frequency GNSS protection with innovative signal authentication, ensuring that ships maintain accurate positioning, even in the presence of hostile interference.
The SAL SPU-200 employs sophisticated interference mitigation techniques, allowing vessels to detect and reject deceptive signals in real-time. This is crucial in environments where GPS integrity is vital, such as congested shipping lanes, offshore oil and gas platforms, and defence operations. The system not only provides protection, but also enables ship operators to receive alerts when interference is detected, allowing them to take immediate corrective action.
“The SAL SPU-200 is a game-changer for maritime security,” Latosinski added. “By providing real-time mitigation against spoofed signals and blocking jamming attempts, vessels can navigate with confidence even in contested environments.”
The Call for Greater Awareness and Preparedness
With GPS disruption becoming a geopolitical tool, AST Networks urges maritime operations to act proactively by implementing resilient navigation technologies. Governments and regulatory bodies must also prioritise this issue to safeguard commercial and defence operations worldwide. The increasing frequency and sophistication of these attacks highlight the urgent need for shipowners and fleet operators to incest in robust and reliable anti-jamming and anti-spoofing measures.
Whilst traditional navigation methods, such as radar and inertial navigation, can provide some level of redundancy, they are not fool proof. A multi-layered approach that includes advanced GNSS protection solutions like the SAL SPU-200 is essential for ensuring operational continuity and security.
As the threat landscape evolves, AST Networks remains committed to providing industry-leading solutions that enhance the resilience of maritime navigation systems. The company continues to collaborate closely with partners, authorities, and vessel operators to ensure that ships remain safe and secure, regardless of the challenges posed by electronic warfare tactics.
