Mysterious interference on satellite navigation systems in the Indian Ocean. The UKMTO asks the commanders of ships affected by the phenomenon to report incidents, providing as much detail as possible. The origin is currently unknown


There is strange electronic interference in the waters of the Indian Ocean between Somalia and the Maldives, affecting satellite navigation systems (PNT). Several captains of commercial ships who travel the routes in the quadrant have reported this. The United Kingdom Maritime Trade Operations (UKMTO) issued a bulletin on 14 November inviting the reporting of any information on malfunctions of electronic satellite navigation systems (GPS, AIS and others). In this regard, the organization asks to provide as many details as possible. Consequently, the incidents of this type that have occurred in recent weeks are not isolated cases, but probably a more complex and multifaceted phenomenon. At the moment, however, the origin of the malfunctions is unclear and above all it is not known whether they are accidental or caused voluntarily by someone/something.
