The ICS Secretariat has produced a short poster, to assist bridge teams when experiencing GPS jamming and spoofing incidents. Members have reported that these incidents are increasingly affecting merchant ships at sea and near ports. Without proactive preparation and mitigation, interference with satellite navigation threatens vessel safety, global trade efficiency, port operations and maritime security.

Developed with input from industry partners, this free-to-download resource, at Annex A, highlights best practice to identify the signs of compromised satellite signals and recommends actions to maintain safe navigation. Bridge teams and crews at large are welcome to download and print this one-page aide-mémoire to display near the conning position on board navigation bridges.
