I am running a RaspberryPI with a DVB-T Stick (nooelec NESDR Mini 2+) which scans the signal on the AIS frequency (around 162.000MHz). Also using SDR VHF, SignalK and Node-RED to process the data. So it's public (in the air) and local (on my machine)... but I saw a video, how you can get such data form marinetraffic.com
Well, second last goal is to extract the .speedOverGround from only one ship (specific mmsi). I'll try the &lookup() function.
The final goal is to have a selectable dropdown list on the dashboard, with all mmsi form the shipData to input the mmsi, that shall be looked up (?? this sounds grammatically weird to me...)
This looks difficult to me, because the entries of mmsi in the shipData changes frequently and I haven't studied the nodes yet... maybe I just work with a text-input . I can get the mmsi from another monitor on the bridge...
My thinking is to store it in another flow. to use it in the $lookup() function...
