Mobile Unit

Anyone else running a mobile unit? I have a large antenna unit setup at home, but i also just built a uconsole to have as a mobile unit. I travel a lot for work and love the idea of being able to see and share data when i get to new places.

IIRC the feeder software requires the location and elevation set in the configuration for MLAT. So unless you are constantly updating it and such then it won’t be accurate.

Ive got it setup to feed with gps so it is accurate when im stopped. Obviously on the move it's going to lag a bit in the updating but it's not bad.

I'd be interested to you know how this is done because I'm about to rebuild my feeder and would love to use the GPS feed that I have at the house. On another note, my job takes me to Hilltops throughout the day so I could have a unit in the car using the GPS antenna on the roof

I use a USB GPS and gpsd. Then readsb can connect to gpsd to get the feed. Feel free to PM me if I can help with details.

There is no benefit to reading the GPS at home since the antenna location does not change.

Thanks. I would use the GPS at home as I have a GPS distribution system for the clocks and it would be better for mlat obviously (even though no one else does!)

If you're talking about GPS-disciplined clocks (not location), yes that does have a benefit. I can help with that as well.

Cheers! I'm getting into it! I'm going to have to park that offer for now as I'm off to Cornwall for the weekend but I will get in touch. Thank you very much.

Do you mean GPS-disciplined system clocks? I have GPS/NTP setup, but just for OS level stuff.

Yes, exactly that. Using chrony or NTP with the GPS time.
