I don't know, I might be inclined towards Edward's view that we should be wary of retaliation against GPS jamming just because your particular transport vehicle didn't have a proper backup navigation system. Losing GPS is not the end of the world (figuratively). It's not like your engine conked out.
The Russians have been fiddling with the GPS and flying unannounced "dark" aircraft into civilian air traffic lanes for over a decade now, and we all deal with it all the time. It's "normal". Just like Russia annexing Crimea was sorta kinda accepted as "normal". Or sending the Russian army into east Ukraine in 2014.
Not responding does not work. Russia just keeps escalating.
However, what has not been tried is raising the threat-profile that something COULD be done.
I mean, part of the reason the Baltic states are bricking it on a regular basis is precisely that they KNOW that there is no credible NATO force even in the horizon that could stop a Russian invasion.
As the Baltics have put it – they want to be defended, NOT "avenged" – at some later point when NATO has got its crap together and ousted the Russian occupiers at least 6-12 months later, when the Russians have asset-stripped the Baltic states down to the bedrock already.
They KNOW they can't hold off Russia on their own. Still, they have all opted for national defenses based on putting as many armed people as possible in holes in the ground, since that is the best way to just hold on to it. And no one but they are going to be around to do it.
That means they have little use for anything like airforce or navy. Others can fly and sail those in pdq instead.
But the reason they keep bricking it, is that the Baltics ALSO know that there really is nothing like a strategic NATO airforce assembled anywhere in the vicinity, or so far on the horizon even, that could come flying in and rain fiery death on a Russian invasion force, in a timely fashion, at scale. Which is why they keep bricking it.
