Per this article, the R-330Zh is being used in Ukraine to jam JDAM:

Can the Ukrainian Air Force's Fencers armed with AGM-45 Shrike take these out? Can its sensors locate GPS jammers?

Is this missile useful at all for Ukraine?

True - more reporting here:

RF homing munitions?

Problem is those munitions will home onto the antenna which may be physically separated from the actual jamming transmitter. Replacing an antenna is easy - just unplug the cable, drive to a new location, set up a new antenna etc.

The other problem is some jamming effects against satellites can be conducted from very, VERY deep in enemy territory. For example, the footprint of a SATCOM system can cover an entire continent which means that a jammer anywhere on that continent can "see" the target SATCOM bird and deliver jamming effects.

I wonder if any of the British ALARM missiles are still available?

ALARM, like most ARMs, is designed to go against air defence radar systems. Could they be adapted to go after jammers? Maybe...but remember that the jammer is targeting friendly frequencies. You'd be programming your ARM to target a frequency that your forces are using. Maybe not the best idea?

According to Wiki (I know...), ALARM is still used by the Saudis.
 
Here's a future AFU F-16 dropping cluster bombs to clear the treeline of Russians.

Ok..just HAD to share this article. Scroll down for the image showing the wigs at Prigozhin's "palace":

Wagner Group: Russian state media takes aim at Prigozhin

Piles of cash, weapons and a giant sledgehammer seen in pictures allegedly showing a raid on his home.

And here's a pic of him wearing one:



Sadly, I can't find a single image online showing Elmer Fudd in a wig. That would have been a useful comparison to the above.

If they are sending out such a strong signal to overlay/jam GPS signals this should be traceable. If Ukrainians are able to trace the source they may need visual targeting help via drone.
If they are out of range for conventional artillery and GPS is jammed maybe there's some option for Laser guidance from a drone.

Russia needs to take out the GPS satellites over Russia. Though I assume NATO and the US have told Russia that's a red line not to cross?

I am fairly confident that GPS and the Russian equivalent, Glonass, use different frequencies but you must also remember the Ukrainians also have Glonass system receivers so killing the GPS satellites would have limited effect - and would immeadiately result in every Glonass satellite falling from the sky which would hurt the Russians more as they do not have the capacity to replace them.
 

Why do they need a strong jamming signal? The signal coming out of the satellites is only about 50 watts. Given attenuation from the atmosphere and other propagation losses, the received signal on the earth is about -125dBm. Doesn't take a lot of power to overwhelm a receiver that's sensitive enough to operate on such a lower-powered signal.
