What’s new: An article, focusing on maritime, about using data fusion to help overcome spoofing.

Why its important:

“The prudent navigator will use all means available to determine their position” – long standing maritime adage incorporated into Rule 7 of the Law of the Sea Treaty
New IT tools have given this new meaning.

What else to know:

The article focuses a lot on what some might call ‘sensor fusion.’
Other types of data might be useful as well, especially for developing SA, COP, and collision avoidance. It would be interesting to read an article that took a more expansive view.

Addressing the Escalation in GNSS Spoofing with Data Fusion

The grounding incident involving the MSC ANTONIA serves as a clear reminder of the critical need for resilient navigation systems in the maritime sector. As GNSS jamming and spoofing become more frequent, particularly in high-risk regions, vessels must be equipped with systems that can maintain accurate positioning even when satellite signals are compromised, explains Freddy Saunders, Senior Data Scientist at Plextek.

Note: GNSS refers to any Global Navigation Satellite System. There are several satellite constellations in use around the world that provide independent positioning estimates including GPS, Galileo, BeiDou and GLONASS.

What Can YOU Do? How Can YOU Help?

PNT is the quiet backbone of everything but too many leaders still don't see the risk.

But you do. You understand the systems, the dependencies, the failure chains. That insight is rare — and it's exactly what your country needs right now. Contact your government leaders and industry decision-makers and tell them resilient PNT isn't a feature — it's the foundation everything else depends on.
