Faup1090 vs piaware/FlightAware lat/long

Greetings!

New to the world of ADP-B, FlightAware, etc. I have a site set up, collecting/reporting, etc. I notice that my latitude/longitude as set on FlightAware.com is out to 5 decimal places, as it is on the command line for the piaware process on my local site.

However, it’s out to 3 decimal places on the command line for the faup1090 process on my local site. As a result of my location in the world, this means the faup1090 lat/long a little south and a little east of the piaware/FlightAware lat/long.

It appears the faup1090 lat/long are what drives the local skyaware web site centering, so this site location is south/east of the skyaware location on FlightAware.com.

Where do I set the faup1090 command line parameters to honor lat/long out to 5 decimal places?

Thanks!

I’ve found where the 3- vs 5-decimal place formatting is occurring (line 24 here), but after adjusting and rebooting, there’s no effect on the local skyaware site; the site location is still showing south/east of the actual site location.

The faup1090 process command line reflects lat/long out to 5 decimal places.

Thanks for any further suggestions/guidance.

Did you try to set the location from the cogwheel at the rightside in the stats page ? I always set it from there and I never have an issuevafter that

Hi,

Have you tried the command option below? The default of 1 only shows approximate location in the receiver.json file, which is likely what is being used to display your home location on the local view. I use package installs, so it is configured in /etc/default/dump109-fa . It might be different if you use a sd-card image. Try 2 for exact.

# Accuracy of location written to JSON output
# --json-location-accuracy <n>
#   Accuracy of receiver location in json metadata
#   (0=no location, 1=approximate, 2=exact)

JSON_LOCATION_ACCURACY=1

Good luck,

Hi - this seems to have been the secret sauce, as now, my site location on the local map is exact!

Thanks!
