I’m confused that there even is a data directory there.
Anyway the actual data is located in
/run/skyview978/
Huh, yeah, where did that come from…
I think I may have accidentally committed some test data, it’s not meant to be there 
Fixed for the next version; as wiedehopf says, the real data is in /run/skyview978/
Same single line entry in /run/skyview978/
pi@piaware:~ $ cat /run/skyview978/aircraft.json
{"aircraft":[],"messages":1182,"now":1555569140.793}
pi@piaware:~ $
At least the date is not bogus
pi@piaware:~ $ date -d @1555569140.793
Thu Apr 18 02:32:20 EDT 2019
Yeah but if you actually receive something it’s gonna be there when it’s in SkyView.
Also the time is hopefully correct

Oh, /run is tmpfs.
I rebooted Pi about an hour ago, that is why the data for aircraft I saw on skyview978 today midday is lost from /run/skyview/, but it is still preserved in my log file uat978.json

Not really, aircraft.json is overwritten every second with a current state of aircraft.
This is then loaded every second in the webinterface.
Tons of .json, but each one has only one entry

I thought you knew the typical web interface, that’s just like the dump1090-fa history files.
Those are used to provide the tracks in SkyView when you open the website.
(30 seconds between history files by default)
That’s also why the turns have more kinks when you first call up SkyView.
While it’s running it get’s data from aircraft.json every second. (and saves a position internally in the webbrowser/website every 5 seconds or so)
(Those history files are just the aircraft.json from the past basically)
If I dont want to stare at skyview978 map for hours, waiting for an aircraft to appear, isn’t the uat978.json a solution? Also is there a way to “playback” the uat978.json to display aircrafts on skyview map?
Well the easiest way is to extend the history function and play that history back.
I’ve done that for dump1090-fa but i don’t feel inclined to implement it for skyview978
In contrast to dump1090-fa, skyview978 even has command line switches to record a longer history. (I’ve added those switches to dump1090-fa in my version)
Anyway the timelapse function is very rough, there is no way to jump to a particular time, you can only adjust the speed.
But that’s a way to do it, you are welcome to improve my code

This is my readout. One plane seems to be popular here. PBR155 is likely the TISB data from a local airport in the US?

I have now updated “graphs1090” by @wiedehopf. In today’s update, graphs for UAT has been added.
If you like, you can also install it by following command:
sudo bash -c "$(wget -q -O - https://raw.githubusercontent.com/wiedehopf/graphs1090/master/install.sh)"
The graphs are displayed in browser at this address (UAT graphs are at the bottom):
ip-of-pi/graphs1090/
Since the installation of graphs till now, no UAT plane flew in my range 
. As a result my graphs are still empty. Will check again in morning.
How do I set the maximum range that is credible? At my 978 feeder stats, I have 5 positions that are over 250nm away. I don’t believe those data.

Is there a way to max out the 978 range?
Only 2 UAT aircraft in last 24 hrs.
Strange, the graph shows both these are only 0.69 aircraft, not even 1 complete aircraft.

It works. I installed this following your instructions and went flying. N14HK has a uAvionix skyBeacon ADS-B UAT OUT. I have the 978MHz rooftop antenna and Stratux 978 and 1090 receivers at my hanger.
For some reason my activity on the ground is not being recorded but this is a great start.
