I found the location of the Baltic Jammer causing flights to lose position, again.
Kaliningrad, Poland (or Denmark). Pick your suspect.
With a new, larger dataset and more refined method I have replicated my results from yesterday.
Data only from when jammer has been active.
A kind anonymous follower gave me data from their own receiver for Dec 8 to Jan 3.
Coverage is still limited but a completely different source. 57'593 observations was included.
This heatmap shows where flights have been recorded and how intense the concentration has been. Only flights with NIC 1-6 are used (representing bad position accuracy, ie jammed)
From this data I identified only hours where the jammer was active (high amount of bad positions). I discarded all hours with low count.
From mean, median and histogram I picked 281 as cutoff for high activity. This excluded 150'523 observations, interpreted as expected errors.
They turned it on. Very curious as to why it is so often nights and so regular.
This might be the explanation for the rhytmicity, it is scheduled?
