Britain urges ships to prepare for life without reliable GPS

Britain has warned shipowners that satellite navigation can no longer be taken for granted in some of the world’s busiest shipping regions, urging crews to practise navigating without GPS as jamming and spoofing become increasingly widespread. The UK’s Maritime and Coastguard Agency (MCA) has issued a new Marine Guidance Note, MGN 719, highlighting the growing threat of GPS interference and the need for ships to have alternative navigation methods.
