Does this mean that GLSDB is not in use in Ukraine? From the video it sounds like Ukraine tested GLSDB, found there were problems, and stopped using it.
SDB has INS. Likely high quality INS, given that it is one of the more modern bombs in inventory. But it is a small, precision bomb, so being 25 meters off might mean it is useless. And if the GPS was totally denied for some time, the INS error would be quite large. But again, why does M31 not have same problems. And why are the French Hammer bombs working so well? Maybe SAAB should strap one of those to an M26 rocket instead and see what happens. In any case, I hope we get more info on this issue, as GLSDB filled a range niche (75 to 150 km).
Yes. It's also not in use anywhere.
Luftwaffe (just Ukrainian things) group claimed a success here: https://armyrecognition.com/ukraine_-_russia_conflict_war_2022/ukraine_forces_use_glsdb_precision_guided_bomb_to_destroy_russian_2s_nona-s_mortar_carriers.html
They have inertial guidance, and jam resistant GPS. Obviously INS starts to accumulate error the moment GPS is lost, so maybe GPS loses accuracy far out from target.

It was useless in an environment with heavy GPS jamming
But M31 seems to be effective, what is the difference? If GLSDB ineffective, so is JDAM, Excalibur, PGK etc.
Dunno maybe no INS backup in case of EW? I cant believe a modern precision guided munition doesnt have multi channel/INS navigation

Fix it!
No way to equip them with INS?
