reported [REPORTED] SCUD lacks INS? Also too Precise but also Inaccurate (TRACKS ADDED)

[Cdodders]

It seems that the SCUD has many issues regarding targeting. 1st is that it needs completely level ground, which may be realistic but we don't have a gradient indicator either in the mission editor or the F10 map. 

2nd is that even with supposedly flat and level ground, such as an airfield, the SCUDs are off target. By the same amount each time, hitting the exact same spot each and every firing.

SCUD B, the model in DCS, is supposed to have a 450m CEP, which means it land anywhere within a 450m circle of the aiming point. Currently it is pinpoint precise, albeit inaccurate as said pinpoint is off the aimpoint. As it is the same point each time it is fired at the same target this cannot be working as intended. 

 

The Scud has Inertial Navigation, which means it should be able to compensate for wind, which in DCS it does not. Even a SCUD dialled in to the intended target by offsetting the aimpoint and testing until dialled in, as soon as wind is added in the SCUDs go wildly off-target.


The image below was such a dialling in attempt. The target is the centre of the runway. Without wind the SCUD strikes the centre of the runway each and every time. The exact same spot but this is where I have to aim in order to get it on the target

TRACKS ADDED

SCUD firing 1 is with offsets added to counter the pinpoint precise but consistently inaccurate FoS - NO WIND

SCUD firing 2 is as above but WITH WIND. No offset for wind used as missile INS should compensate automatically

There should be a dispersion from the CEP = 500 m. That is, 50% of the missiles fall in a circle with a radius of 500 m around the target.

 

Please include a track replay we will take a look

 

thanks

Right now SCUDs hit the same spot over and over again. Expect tracks soon.

Any progress on this?

[Grimes]

Nope.

SCUD missiles still missing its coordinates of impact point with even 5 nautical miles (9 km). This is NOT about dispersion... there is BUG.

Also SCUD wont to engage group even when friendly unit near by (as source of data for SCUD launchers).

Bug still present

Please can the scud missile be updated/corrected. I would create many more missions with this asset, however, it is too inaccurate ant they tend to hit the same spot. It would be so cool for some corrections to be made on this model. Such a shame as it looks fantastic.

Still an issue or maybe even worse now?!

I've created fire at point in a Syria map mission but missile launches flying to the east when the designated target point is west of the launchers.

SCUD has ALWAYS been spray and pray in my experience...

Thanks for pointing to the mission editor post.

In my mission the Launcher moves some waypoints and than at the last waypoint has the fire at target action.

I now figured out, that the launcher vehicle needs to face in the direction of the intended target. If the launcher is facing 90° off target or even more, the missile will impact 30km away from the target or even totally flies into a different direction.
