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.
