Hmmm....? Sounds like I forgot to refresh the map when the position of an ADS-B station changes its position.

You can work around this by checking the menu choice View->Map Layers->Show Age. This adds a small-font display of how long since the last update for each station or object. Since that has to be updated regularly, that should cause the station positions to be updated more frequently.

Hope this helps until I can get the fix out.

Greetings Andrew -

Thanks for integrating an ADS-B viewer into YAAC. I run an ADS-B receiver in the truck, and especially when I'm out in the middle of nowhere it's nice to be able to ID aircraft that happen by. I was using the browser interface to my ADS-B program running on an RPi on the truck network, but now that I have YAAC going I can watch there as well!

YAAC is running on a W11 Pro box in the truck, connected to the same truck network.

I've been noticing that a/c icons sometimes rarely move on the map unless I rescale the map or refresh it in some way. For instance, SWA5641 is moving past me at about 20ft and the "Monitored Aircraft" list shows the lat/lon updating once a second or so, but the icon on the map rarely if ever moves, and it always shows a staleness of "0s". That's just one example, there are dozens on the list many moving quickly, but letter to nothing moves on the map. Sometimes, maybe, they update quickly (like if I do a locate).

I did a search for ads-b related stuff on this reflector but didn't see anything about tweaking map update rates. Could it be that YAAC is just overwhelmed? I'm seeing over 350 a/c right now, according to the list.
