From Signal Warfare to Safe Passage: How Resilient PNT Creates Confidence

Maritime operators don't have to wait for the next navigation disruption to act. Trusted positioning, navigation, and timing (PNT) data is available today — even in environments where traditional satellite signals are challenged — and it's already helping fleets navigate with confidence.

This shift comes at a critical moment. Over the past several years, satellite navigation interference has moved from a theoretical risk to an operational reality. Nearly 10,000 suspected GNSS spoofing incidents affecting more than 1,300 civilian vessels have been recorded across the Mediterranean, Black Sea, and Baltic regions alone.¹ More recently, disruptions have been reported in the Persian Gulf and Red Sea amid heightened geopolitical tensions. Even outside conflict zones, interference has been reported with growing frequency near major ports and dense shipping corridors.

These developments underscore a simple truth: satellite navigation now operates in a contested electromagnetic environment.

From Electronic Chart Display and Information System (ECDIS) and Automatic Identification System (AIS) to dynamic positioning and voyage optimization platforms, modern maritime operations depend on continuous, high-integrity PNT data. When GNSS signals are degraded or manipulated, these downstream systems can inherit incorrect positioning information, sometimes placing vessels tens or even hundreds of miles from their true location. In congested waterways, even brief uncertainty can have significant operational consequences.
