GNSS Threat & Resilience Assessment
Your fleet depends on GPS — but GPS isn't reliable.
Assessment of GNSS dependency, interference exposure and existing mitigations for fleets, VTS and port systems. PNT resilience roadmap with multi-constellation approach.
The global surge in GPS spoofing (+510% in 2025), persistent interference in the Baltic from the Kaliningrad region, and GNSS degradation in the Black Sea raise the question: how resilient is your navigation system to interference?
We conduct a comprehensive GNSS dependency assessment for fleets, VTS systems and port infrastructure. We map vulnerability points, assess existing mitigations and deliver a PNT resilience roadmap — from multi-constellation receivers through degradation procedures to backup sources.
Our approach combines maritime cybersecurity with radio systems, navigation and IMO/flag state regulatory knowledge.
Benefits
- Dependency mapping — complete picture of where and how the organization depends on GNSS
- Exposure assessment — interference risk analysis for specific operational regions
- Resilience roadmap — layered PNT architecture (GNSS + INS + terrestrial + radio)
- IMO compliance — alignment with flag state guidance (e.g., Republic of Marshall Islands)
- Operational readiness — procedures for PNT loss, crew training
For Whom
- Shipowners — fleets operating in the Baltic, Black Sea, eastern Mediterranean
- Port authorities — VTS and traffic management systems
- Offshore operators — platforms in interference risk zones
- VTS operators — maritime traffic control centers
What We Deliver
- Inventory of GNSS-dependent systems
- Interference exposure analysis (per operational region)
- Assessment of existing mitigations and gaps
- Prioritized PNT resilience roadmap
- Hardware and procedural recommendations
- Results presentation for management
