Two words mentioned by the Mexican drug policeman who boarded the container ship were AIS and Inmarsat.
The automatic identification system (AIS) is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS). AIS information supplements marine radar, which continues to be the primary method of collision avoidance for water transport.
Inmarsat is a satellite-based telephone and data service for governments, aid agencies, media outlets and businesses, especially shipping, who need to communicate in remote regions or where there is no reliable terrestrial network.
