Hello Felix -
The AIS data stream you illustrate looks like raw 7-bit encoded NMEA-0183HS AIS data.
The GeoEvent Extension does not provide an adapter which is capable of decoding this format.
NMEA-0183HS messages are a variation of the NMEA 0183 data standard. They are 7-bit encoded ASCII messages which are not human readable. While they are part of the broader NMEA specification, they are not what common consumer devices like Garmin or smart phone applications broadcast.
The NMEA messages the GeoEvent Extension is able to ingest are 8-bit NMEA-0183 messages which typically look more like the following:
The full NMEA specification details a variety of different message sentence structures. There was a pull-request, for example, on the Esri / nmea-for-geoevent GitHub project to modify the sample connector we have on the gallery to support RMC sentences of different lengths.
Having open-sourced our NMEA implementation, developers are able to tailor the connector to match their device's sentence structure - if what they are receiving does not happen to match the GGA / GSA / GSV / RMC sentence structures illustrated above.
Since the NMEA-0183HS AIS data you are receiving cannot be adapted by the NMEA connector on the Gallery, have you considered the exactEarth Latest Vessel Information connector available from the Partner Gallery?
