Maritime Dangers of GPS/AIS Spoofing and Jamming in the Baltic Sea

15 July 2024

The second quarter of 2024 has seen a significant increase in electronic warfare activities in the Baltic Sea, particularly involving GPS and Automatic Identification System (AIS) spoofing and jamming. These activities pose a significant threat to maritime navigation, affecting both commercial and military operations and reflecting the heightened geopolitical tensions between NATO and Russia.

Baltic Sea Dynamics

The Baltic Sea has experienced an upsurge in GPS and AIS jamming incidents. Several reports are known of aircraft and commercial vessels losing connection to electronic positioning systems across the Baltic Sea. These activities are primarily attributed to Russia's strategic positioning around Kaliningrad and its response to NATO's expanded presence following the inclusion of Sweden and Finland into the alliance. The jamming affects both civilian and military navigation, leading to increased risks of accidents and operational inefficiencies. The Baltic Sea's dense maritime traffic and its importance for NATO's eastern flank make it particularly vulnerable to such electronic threats​.

The increase in GPS and AIS jamming incidents has significant implications for commercial maritime traffic in the Baltic Sea:

  • Navigation Disruptions: Jamming and spoofing interfere with the accuracy of navigational systems, leading to potential misrouting, collisions, and grounding of vessels. This poses serious safety risks for commercial ships operating in the region.

  • Operational Delays: Disruptions in navigation systems cause delays in shipping schedules, affecting the timely delivery of goods. These delays can lead to increased operational costs and economic losses for shipping companies​.

  • Increased Insurance Costs: The heightened risk of accidents and the potential for cargo loss or damage due to navigation errors may lead to increased insurance premiums for vessels operating in the affected areas. This adds a financial burden to shipping companies already dealing with operational disruptions​.

  • Supply Chain Impact: The Baltic Sea is a critical corridor for trade between Europe and other regions. Disruptions in this area can have a cascading effect on global supply chains, affecting the availability and cost of goods​

Russian Hybrid Threat Effort

The recent increase in GPS and AIS spoofing and jamming in the Baltic Sea is part of a broader Russian strategy of hybrid warfare directed against the West. Hybrid warfare involves a combination of conventional military force, cyber attacks, misinformation, and electronic warfare activities to achieve strategic objectives without triggering a full-scale military response. The goals of such a campaign likely include, but is probably not limited, to:

  • Undermining NATO Cohesion: By disrupting navigation systems and creating uncertainty, Russia aims to test NATO's response capabilities and unity. Persistent electronic interference serves to undermine confidence in NATO's ability to protect its member states and maintain secure navigation routes.

  • Cause Economic Disruption: Targeting commercial maritime traffic through electronic warfare is a tactic to create economic instability. By increasing the operational risks and costs for shipping companies, Russia seeks to exert economic pressure on NATO countries and their allies​.

  • Psychological Impact: The continuous threat of GPS and AIS jamming contributes to a climate of fear and uncertainty among maritime operators. This psychological pressure is intended to weaken the resolve of NATO members and create divisions within the alliance​. In addition, Russia using electronic warfare systems in the region is likely part of an effort to shape the perception of the Baltic Sea as a contested area, rather than simply predominately being under NATO control – especially since Sweden and Finland added significant capabilities to the region.

In summary, the escalation of GPS and AIS spoofing and jamming in the Baltic Sea represents a significant challenge for maritime navigation and regional stability. These activities are part of Russia's broader hybrid warfare strategy aimed at undermining NATO and exerting economic and psychological pressure on the West. Addressing these threats requires a coordinated and strategic response to ensure the safety and security of maritime operations in this critical region​
