A recap. Satellite transmits a clock code and trajectory, based on detailed measurements on the difference vs a local clock, distances to satellites can be calculated. There are much more to this to get a precise measurement, adjustment for difference in speed of light through iono and troposphere,

Data is published in RINEX format, essentially containing the time codes for signals, measured signal strength, doppler shift, this can then be analyzed in many ways. Here we see signal strength vs angle over horizon. Should normally follow fairly well

This is Hoburgen data. Signal strength is OK, satellites supposedly over horizon. Code residuals are very consistent for a solution

The shooting lines happens when solved for the satellites marked below. Plotted are "code residuals", ie difference from calculated time distance vs calculated distance based on satellite trajectory and known position of station. It should stay at zero, but time signal is shooting off

I revisited June 14, known noisy day, with new take on resolvers. These are Rinex data from stations Hoburgen, Bornholm, Gdansk and Braniewo. Note the shooting lines, these are valid solutions, but diverging from station

What we see here is signal strength per satellite over time as it is panning over the sky. The disruption is when the spoofer takes over, we do not see the characteristic increase/decrease when satellite passes, the spoof signal is irregular

I was having a look at traffic gps data for central Moscow. It is really crazy, wherever you go, you will be teleported. But here are some highlighted hotspots. Red means high jam ratio

Ducting is a very seasonal effect, but one idea may be that they are targeting tropospheric scatter, firing fairly high energy signals at sky that will distribute at high ranges, ”raining down” on receivers

Traffic in Ust-Luga region. GNSS disturbance at the oil terminal hit a month ago. The Kingisepp jammer may be located either at the Fosforit plant, or in center, close to fuel depot and railway. I do not know if the Kyorstovo air defence site is in play here, but notable it is in vicinity
