need track replay Maverick boresight error doesn't follow airplane orientation, instead it is north / south / east / west

[TobiasA]

I have no idea why I can't save tracks, that feature somehow got broken and it copies the same track over and over again. I am unable to save tracks, it just saves an old one each time, no idea why. Will try to fix it. So maybe someone can record a track for this.

I think I found out that if you boresight your mavericks flying south to north, then boresighting the mavericks will have a slight error along the length axis, so it will deviate a bit before or aft of the target (little bit to the south, little bit to the north).
If you now attack from east to west, the error will be to the side (still a bit north or a bit south, instead of long or short of the target), and maverick handoff will fail, because the error now matters, and you will land a significant distance away from your target. The error needs to be a angular one, not meters to the north / south / east / west something.

Steps to reproduce:
- Align your mavericks in the air, flying south to north. Check if they return to the target with TMS down, they will.
- Now fly around that target, and attack the same target with a 90 degree offset (west to east). You will see that your mavericks are now shifted left or right.
- Attack from the south, and alignment will be better again, because the error doesn't matter as much now (as you are a bit in front of or aft of the target, but the seeker will still point right at it)

Maybe someone can test that and record a track... Because my track feature broke. Attached a mission file to test, there is a single target a bit south of the others. Boresight your mavs and that target, fly out east and notice the direction and visible amount of the error.
Let me know if you see the same or not. Sounds weird, I know... So thanks for taking a look. Hope my description was understandable.
Tested with the ATP but I'm pretty sure it's the same with the Litening.

Hi, 

we are going to need a track replay to understand what you are doing. 

How far are you from the points used for reference? Are you pointing your TPOD to the base of the chosen object, or centre mass? According to your description, it sounds you're not considering parallax errors when performing the procedure and, therefore, have a deviation. But this is speculative without a track.

 

To create a track replay fly the mission, reproduce the issue, then exit the mission, during the debrief window you will see an option to save track, then you should have that track in your saved games dcs track folder. 

 

thank you

I tried just that, I saved tracks earlier, but it saves the same old track over and over again.

One from last year...

Don't know why.

I am 7nm out.

Can you attach your dcs log please 

and have you disabled track replays in your autoexec by any chance?

My genius is frightening, sometimes in a positive way, sometimes in a negative way. Thanks for pointing that out, I forgot about that. Stupid me copied the file from a buddy.

Attached is a track.

I align south to north. I can handoff my mavs.
Then I turn to the left, and fly in from the west. The target is offset to the left, the maverick points to a point south of the target. Handoff kinda works at larger distances, but not a bit closer, because the lateral offset becomes too large.
I fly over the target, come in from the east, and target is now offset to the right, maverick still points south.
I come in from the south, I can handoff.
So the mav doesn't have an angular offset but an offset in north / south / east / west direction which would explain why people like me that align mavs on their way in, usually in a different direction as the final attack, almost never are able to handoff, and other people never have this issue. It should be an angular offset, like always 0.003 degrees to the left and 0.05 degrees up, or probably depend on range since TGP and mavs aren't in the same axis. It should not be "always south".

Drop me a line if I messed up the track, I think it worked now.
