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.
ASTROL 1 is a largely flat cargo ship with hatches that likely would serve well as drone pads.
She is a similar model to SCANLARK, recently apprehended by German authorities on drone suspicions and to PORT OLYA 4, drone import ship on Iran trade. Sunk by Ukraine.
