The automatic identification system, or AIS, transmits a ship’s position so that other ships are aware of its position. The International Maritime Organization and other management bodies require large ships, including many commercial fishing vessels, to broadcast their position with AIS in order to avoid collisions. Each year, more than 400,000 AIS devices broadcast vessel […]
Analysis of tracking data from automatic identification system broadcasts reveals vessel locations have been simulated for a number of ships, including military vessels. This false information could compromise vessel safety, decrease confidence in a crucial collision avoidance system and potentially spark international conflict. Over the years, data analysts working with Global Fishing Watch and SkyTruth […]
Global Fishing Watch has launched an improved version (v3.0) of our automatic identification system (AIS) data pipeline. The AIS data pipeline is the series of processes that we use to convert the raw satellite AIS ingested data to the data products, such as machine learning estimates of fishing activity, identity data that combines merged external […]
Sublicensee has a non-exclusive, non-transferable, worldwide license to use certain Automatic Identification System (“AIS”) global data collected via the ORBCOMM system of AIS equipped low-Earth orbit satellites and other AIS data sources (the “AIS Data”) for (1) non-commercial purposes including, but not limited to, research and educating the public concerning illegal fishing activity, including for […]

Analysis from SkyTruth and Global Fishing Watch shows ship tracks jumping thousands of miles from their true locations. Bjorn Bergman works with SkyTruth and with the Global Fishing Watch research team to track vessels broadcasting false automatic identification system (AIS) locations and to investigate new sources of satellite data for vessel tracking and for detecting […]
We are often asked about how Global Fishing Watch can be effective when vessel captains can simply turn off their AIS. And our answer has always been, “they have to turn it back on sometime—especially when entering port, and intentional blackouts raise a red flag.” Our recent analysis of fleet activity around the Argentine EEZ […]
