Ingame, IOG+GNSS is handled as simply IOG with zero drift.
Regardless, there’s not really a fallback condition for IOG/GNSS, its for initial launch behaviour.
You can test it by firing Kh-38ML’s in laser mode, and then immediately disabling the laser. It doesn’t fallback to GNSS it just crashes into the ground randomly. The laser already overrode the GNSS input.
Similarly, the LMUR’s are currently bugged and will frequently lose lock the second you launch them. Despite having IOG and GNSS, they fly off into space or crash into the ground randomly. They don’t fallback to either GNSS or IOG.
Laser guided weapons do not have inertial guidance as a fallback. This has been the case for a long while. IR and TV weapons do fall back to this situation.
It really isn’t. 38 falls back to inertial guidance fine, which is especially obvious under 10km. A target can be obscured by smoke, a building, etc, but upon no longer being obscured if they followed the same path as the inertial guidance predicts it will reacquire the target. If it can’t find the target, it will follow inertial guidance into the incorrect impact point.
If it’s behaving incorrectly, report it. With the amount of tweaking LMURs have gone through recently, it’s entirely possible someone broke it.
You are just wrong here. Terminal phase just hitting near it would not re-engage the tracking on an obscured target that leaves that position from significantly further up without inertial guidance being the fallback.
But I really don’t care enough to continue this. Being wrong is the prerogative of folk like you, and every demonstration under the sun could prove it thus, but folk like you would still cry “But it’s not like that”.
TV and IR munitions can reacquire targets near the crosshair, that’s normal behaviour. Its not guaranteed though
Similar to the Kh-38MT, Spikes can glide in and hit targets after losing lock to smoke for example, its not a fallback condition, they don’t have one, they’re just on a terminal glide path.
And similarly to the LMUR, the Kh-38MT’s can lose lock early and either fly off into space or crash into the ground randomly.
