Question to the Department for Transport:

To ask His Majesty's Government what steps they are taking to provide training or other safety provisions for British Merchant Navy crews to deal with GPS jamming and spoofing; and what measures they are taking to ensure the safety of British waters in the face of those risks.

UK seafarers are trained to use back up navigation systems, including celestial navigation for deep sea voyages and radar and visual fixing techniques in coastal waters, along with all other standard navigational aids. Training on recognising and responding to GPS jamming and spoofing is also an integral part of the competency requirements for those working toward a UK Certificate of Competency.
