So i’ve added experimental GPSD support to readsb / tar1090 (only in that combination).
(Raspbian Lite: ADS B receiver · wiedehopf/adsb-wiki Wiki · GitHub)
This needs to be added to the readsb configuration:
--net-connector localhost,2947,gpsd_in
You can press H on the tar1090 map and it will follow the changing location automatically.
The dot and rings will be updated independently of pressing H.
