Finally got access to #chatgpt and got it to write some #javascript for me. A bit to calculate elevation of an aircraft and a bit to calc the normalized inverse square of a radio signal.
I put both bits in a function node in #nodered and plotted the result.
So now I have a radar plot of aircraft distance and signal strength to show changes to my #VHF #VDL2 station.
I could not have written this code, so its a pretty big deal in my books.
Monitoring VDL2 this evening using #MultiPSK and a RTL-SDR V3. Frequency is 136.775 MHz.
Usé mi #RTLSDR y DumpVDL2 en Linux para revisar si habían mensajes VDL Mode 2 de vuelos comerciales en la frecuencia por defecto (136.975 Mhz) y sí, hay bastante actividad.
Here is a screenshot of lat/lon from aircraft plotted on a map.
There are two #ACARS stations here, #KLAS and #KPHX airports.
Using #nodered worldmap node and its heatmap to show traffic density.
Ok, just added one from the UK as well... a single #ACARS #VDL2 station in this case.
Keep in mind some of these aircraft will be using #ADSB, some wont <cough Elon /cough>.
