Why is Ukraine not jammed in this map? Shouldn’t that be Russia’s priority?
The GNSS jamming in Ukraine is mostly from Ukraine themselves, to defend against Russian drones and guided bombs.
Just as Iran jams GNSS, and Venezuela jammed GNSS ahead of the attack. Didn't really help though.

Probably because Wester jammers are used from ground and drones have antennas on the top side. For comparison, Russian satellite can jam the signal from above and on a large area. Russian technology is superior.

GPS interference is estimated from ADS-B data which is broadcast by airplanes so that they can be tracked. The lack of data over Ukraine is because their airspace is closed to civilian flights.
They would be jamming their own glide bombs and drones then. It would be more useful to jam Russian airspace to defeat Ukrainian drone attacks.
