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?

As mariners, we share the sea with countless marine creatures – yet we often overlook how our vessels impact their lives. As responsible seafarers, this is an issue we can no longer ignore. Captain Aly Elsayed AFNI, from the IWC expert panel on preventing whale strikes, looks at some of the dangers that whales face and how we can help keep them safe.

The WWF and its partners present a global view of blue corridors for whales, combining satellite tracking data from over 1000 tags from 50 researchers. They help uncover the migration pattern of whales and their critical habitats.
