George Shaw from the Royal Institute of Navigation explores how GNSS can become vulnerable to jamming and spoofing and what mariners can do to stay on course
The Navigator
In this series, we take a look at issues affecting the safety of mariners and the lessons that can be learned from incident reports and examples. The following case studies and analysis have been provided by Gard P&I Club

Far from being a theoretical concern, recent incidents in geopolitical conflict zones have underscored the very real and immediate dangers posed by compromised global navigational satellite systems (GNSS).

GNSS such as GPS, GLONASS, Galileo and BeiDou are key elements of positioning, navigation and timing. Their signals, however, can be affected not only by unintentional interference but also by intentional jamming. The growing reliance of ships on GNSS means that seafarers need to be aware of how GNSS jamming happens and how to detect it

Do you know where your ship is? Now imagine that the satellite navigation system has failed, and the position is now longer marked on the ECDIS – or is showing as somewhere the ship cannot possibly be. Now what happens?

Deck cadet Chelsa Maria George Paul talks about her experiences at sea, her ambitions to rise through the ranks and her desire to be a good role model for women all over the world who want to build a career at sea.

Space and AI technologies are increasingly able to provide information that helps mariners plan routes to avoid whales at sea – but old-fashioned look-out skills are still needed. George Shaw from the Royal Institute of Navigation investigates further.
The Navigator
Whale strikes remain a concern for all seafarers, as does the protection and conservation of these marine giants. Read on for some useful links, tips and resources to help you learn more about avoiding strikes, understanding the habits of whales and factoring their preservation into passage planning.
