Project description

IF YOU HAVE AN URGENT OPERATIONAL NEED: Email or call/sms +1-415-598-8226

Screenshot of AIS points in ATAK-Div Developer Edition.

aiscot receives AIS Sentences from an AIS Receiver, such as ais-decoder, converts them to Cursor-on-Target Events, and transmits the CoT Events to a destination.

For use with CoT systems such as ATAK, WinTAK, etc. See for more information on the TAK program.

Utilized for an open ocean boat race in the Northern Pacific Ocean, as described in this article:
