I’ll definitely consider joining it at some point, Thanks!

and the Paveway IV has been denied Data-link

and I really dont understand why.

The way I would implement DL is to simply remove the range limit on the laser spot updating the target point.

But I just dont understand why laser-guided bombs are classed as not being “man-in-the-loop” and its fine the GPS coordinates can be updated when within laser spot range (about 4km from target). But its considered “man-in-the-loop” when you want to update the target from further out

So then isn’t the question, why in their words do SALH guided PGMs (e.g. Paveway II / LGBs) not count as “Man in the loop”? As their point of impact can obviously updated Post-release.

Or even Brimstone Dual-modes

I guess what they define as man in the loop, is a self homing terminal seeker (TV/IR/MMV/GNSS) changing its target by the player will.

None of those could be classified as man in the loop. The bug manager just doesn’t know what he is talking about.

Read my whole comment

But we already have SALH+GPS configurations, in the GBU-54 / -55 / -56 (L-JDAM)? Which obviously permits post release retargeting.

I know what you said but self homing doesn’t make sense. Cause you are not in control after drop. So “them” using that as man in the loop doesn’t make sense.

After seeing the laser, GPS is turned off, instead it is flying on IOG, so technically you are not changing GNSS, but laser IOG.

Example.
PGM (the bomb with rocket boosters) can be launched as stand off, by locking a target, but mid flight, operator can take control over the targeting system, and change the seeker target, Man in the loop.

They do not implement man in the loop, that is changing the target of TV/IR/MMV/GNSS target.

Isn’t it’s deviation see to “0”, though? so it will always perfectly maintain intercept geometry.

Yes, but it is still technically not GNSS, but the laser seeker within the 4km range. Outside of the 4km range you cant change the GNSS target.

While we don’t have man in the loop, the Paveway IV should function like it without needing it because IOG should be so great that there’s functionally no deviancy. GPS aided IOG weapons should have no deviancy from the last laser spot track even if Gaijin does not allow players to change the GPS coordinates themselves.

Inertial drift significantly reduces with the addition of GPS mechanisms. There should be paper on this.

They do have 0 drift. Or at least they had

Ok I see you are referring to the DL. My bad. Yeah Gaijin doesn’t seem interested in DL with A2G munitions. That being said laser guidance by definition is a man in the loop.

Are you ever going to realistically be able to find a 2nd target then ensure the JDAM has the energy to reach the target that far away from the original point of impact.


Also it’s not just the P-IV’s with GPS retarget, the P-III and EGBU / P-II+ & later production JDAM (and more) kits also have the capability.

Maybe I should report the JDAM’s timeline(e.g. fin unlock etc.), being too short.

I think it gets mentioned somewhere in the above paper. Excerpt from PDF Page# 43.

Optimal guidance is through the use of a combined INS/GPS guidance solution, to achieve a 13-meter CEP at impact angles greater than 60degrees. However the weapon may also be used in an INS-only mode when employed in a GPS-denied environment. The accuracy of the weapon in the INS-only mode would be reduced to a 30 meter CEP

additionally there is Table 5-1 on PDF page #48.
