Today the Baltic Jammer changed. Starting with normal characteristic yesterday, after running for ~11h 0720Z there was a sudden change in area affected.
A NW sector of about 140°-180° is spared from GPS-jamming since then. It has made the problem almost exclusively Polish.
Still images of the periods before and after 0720 this morning. Each dot is a message of NIC 1-6 (low GPS quality).
The Estonia area is another jamming process, with other temporality/spatiality. It is almost always on.
Me and @rundradion discovered it about the same time from our plots.
Suddenly the metrics were different, not clear, not fully on.
When its off the % is at 0 with very few blips, see the period preceeding yesterdays start up.
The process-change could be confirmed at globe.airplanes.live/?badgps and globe.adsbexchange.com/?badgps who uses another detection algorithm. Forgot to screenshot though.
As I write this post, they have changed back...
Look at the plot above and you can see how it changes on the very last data points. Can be followed live at globe.airplanes.live/?badgps
