Combining multiple receivers into one map - Combine1090

[jaymot]

Read the instructions in the readme page of GitHub - wiedehopf/combine1090: Combine data from multiple ADS-B receivers into one readsb decoder / tar1090 webinterface. When you open the config file in a text editor it tells you what to do. Just look at the examples there.

What changes are needed to the configuration file needs to be made to except the basestation data on port 29109?

So I’m back to playing around with combine1090 again, installed it on one pi and pull data from its local instance as well as my production FlightAware feeder. I’ve also been able to get the map settings similar to the SkyAware view. However, I can’t seem to figure out how to (1) change the web page title from “tar1090”, and (2) enable the links to load FlightAware data instead of PlaneSpotter. I see the options in the config.js (I see more than one), but it’s not clear on the steps to take, as combine1090 seems to invoke the tar1090 installer without my ability to configure anything. So which (git or html-combine1090) file to I edit and from where do I re-run the tar1090 install script and with what parameters?

Thanks,
Erik

You already found the html-combine1090 … why not just edit that and see if it changes anything.
When changing config.js, no need to restart or reinstall … it’s loaded by the browser.

Accounting for all possibilities in those configurations and readmes is … meh
But i suppose combine1090 could have a noet about the correct config.js

Hmmm, I did try that but it didn’t work. However, it appears that stuff is being cached as when I opened a separate private browsing window it did work. Clearing the browser cache for that IP address seems to have fixed the issue.

As for the flightawareLinks setting, that does change the links on the right flight list, but is there any way to get the left side popup to use that data as well? Often planespotter has no image data, yet I know flightaware does (many flights have pictures from me…).

config.js is explicitely not cached so a simple F5 should be sufficient.
Are you certain you edited the correct file and didn’t make any javascript syntax errors?

You can only have FA image links, not get actual images.
They should show on the left, you might need to disable the two thumbnail loading options.

Combine data from two raspberry Pi, on a third Linux pc but on map in Legend menu don’t found the choice “actual range outline”. How to enable it?

Hello @wiedehopf,

First of all, thank you very much for your brilliant work and the great software you are gifting to the community!

Quick question: what does the turquoise blue polygon in combine1090 shown in below example indicate? It seems undocumented and I fail to make any sense of it.

Many thanks for your response in advance!

[foxhunter]

It is the same as for tar1090
The area shows in which distance you have received aircraft (signal).

It is called actual range outline and shows the range during the last 7 days.

[cvdr]

Thanks. It appears that this range polygon is calculated with some delay (see above screenshot where there are plenty of aircraft outside the same) which is why I didn’t grasp its purpose.

But now that you mention it was the same as in tar1090 - I’ve actually never seen the range plot in tar1090. How do you enable it there? Can it be shown in parallel to the heywhatsthat.com range outline (which I’ve enabled on all my instances of tar1090)?

last 7 days.

last 24h is default.

The “delay” is just waiting for the aircraft position to be 100% certain.
That avoids spikes when there are wrong positions calculated which happens now and then.
And it updates every 15 seconds or so.

It’s a feature for readsb with tar1090.
Not gonna work with dump1090-fa as that doesn’t produce the necessary data file.

oh really? Then i obviously misread it. Sorry

[wiedehopf]

I guess the only mention is in the readsb help:

      --range-outline-hours=<hours>
                             Make the range outline retain data for the last X
                             hours (float, default: 24.0)

It’s also mentioned in the tar1090 wiki indirectly in the history section.

My bad

Hello world,

I installed combine1090 on another setup on the weekend and noticed that no MLAT positions are shown from the remote feeder. Would it be possible to get these as well?

Thanks!
