Hello everyone,
Now my reciever is able to see aircraft but my ads-b graph is empty
Is this because of no GPS or MLAT synchronous issue.
Test your dongle
(1) Install test package
sudo apt Install rtl-sdr
(2) Stop your decoder (readsb or dump1090 whichever you have installed)
(3) Issue following command and post it’s output
rtl_test -t
Seems to me like insufficient data. Or, the range graph is just pinned at 0.
“Aircraft seen / Tracked” graph indicates that over four hours, there were five brief moments in which your receiver was receiving data from one plane. Similarly, “ADS-B Maxima” shows your receiver only occasionally reaching 0.1 message per second.
The receiver is performing very poorly. There is a problem with either your hardware or configuration.
