This is a simple AIS parser that reads a UDP stream from aisdispatcher parses it into JSON and posts the output via http to the aprs.fi endpoint.

requires libais: https://pypi.org/project/libais/

aprs.fi accepts the ais message in the following format:

{"protocol": "jsonais", "encodetime": "20131231235959", "groups": [{"path": [{"name": "MYACCOUNT", "url": "http://www.example.com/" } ], "msgs": [{"msgtype": "18", "mmsi":123456789, "callsign":"C4LL5GN", "shipname":"MY BOAT NAME", "shiptype":37, "status":5, "speed":0, "lon":0.00000, "lat":0.00000, "course":0.0, "heading":0.0, "length":12, "width":2, "ref_front":6, "ref_left":1, "draught":1, "rxtime":"20131231235959" } ] } ] }

1. Receiving the data from the receiver: use AISDispatcher (http://www.aishub.net/ais-dispatcher) to recieve the stream on your machine.

2. Decoding raw NMEA messages: use ais_json to decode and upload data to APRS.fi.

This code reads the AISdispatcher UCP stream, so for example, set AISDIspatcher output to PORT = 5000, IP='127.0.0.1' this script (ais_json) needs to be running in the background.

edit settings.py to include your aprs.fi account name and SeCrEtKeY

Your AIS SeCrEtKeY can be found in https://aprs.fi/account/ under "AIS password"
