Discussion Space Shuttle Vessel - Payload Development Thread

[gattispilot]

Ok. I was hoping just to attach it to the pdp to rms to check camera alignment.

What does it mean "Attached vessel does not match vessel in scenario data"

The grapple fixtures of the PFTA should be to spec, you can check your dimensions against them.

What does it mean "Attached vessel does not match vessel in scenario data"

I means that the scenario parameters don't all match.

 

[gattispilot]

Ok. this is what I was testing.
the rms is attached the the PDP for sts 3. It looks like the camera target needs to move.

oh so in the scn the payload needs to be added. Now the camera aligns

 

[gamer19]

any idea why am I either getting CTD or mission starts but can't see Shuttle anymore at all ?
it's just a blank space. and I've never seen this before. everything loads fine but shuttle

and I believe I have everything installed.

Which versions of Orbiter and SSV are you using?
Do all SSV scenarios have this issue?

 

[gamer19]

latest SSV I believe
and O2016

* Changes from SSV v1.11 *
replaced dead Flight Data File page link with archived version
small code cleanup and corrections....

that's from read me, so I guess it's the latest

couple just CTD, the rest don't show SS

btw, I'm a pretty much noob about this, sorry, so SSV is not the same as SSU (ultimate) right ?
those (SSU) scenarios don't crash, it seems

 

[GLS]

latest SSV I believe
and O2016

SSV v1.10 is the last one for Orbiter 2016.

 

[gamer19]

god god...
sorry
back to 1.10

 

[DaveS]

Yes.
Initially I was thinking the alignment might not be good enough, but actually that might not work at all. The IECM vessel is already attached via a "parent" attachment (only one parent is allowed). When the vessel is attached directly to the PLB via the active latches, there is a "handover" between them and the RMS, thus working around this limitation.
I'll have to figure something out for this situation... thanks for catching it! Meanwhile you'll have to release the IECM from the pallet and then grapple it with the RMS.

I've been thinking about this and I think the best way would be to externalize all systems stuff, VC elements included. Currently, everything is internal to the main SSV DLL module, which I think unnecessarily complicates things as things much exist both internally and externally at the same time. Once upon a time there was an add-on developer, Radu094, that came up with what I have always thought to have been a brilliant solution to this problem. It was called the "System&Panel SDK" which allowed for complex systems and at time, 2D panels, to be developed outside DLLs, in regular cfg files.

Unfortunately, it fell by the way side and was all but forgotten about. But the problems presented in this thread finally lead me to dig up Radu094's old site from 2005 (20 years ago) and thanks to the Wayback Machine, it can found archived here, with all the links working: https://web.archive.org/web/20060215040008/http://217.10.196.198/Orbiter/main.html

Would something like this work for SSV?

The SPSDK is very interesting, and it is a shame it wasn't continued... maybe it could be integrated into GenericVessel or VesselBuilder or some other similar framework, to expand their capabilities.
For SSV, it would require many more features, and very likely it would not work as well as code, and for sure it would be slower. Also, not sure how it would handle different system configurations, interface with the DPS, etc... and in the end, I don't know what problem it would solve.

Back to the RMS issue, this SDK would not solve this issue. The Orbiter attachment logic does not contemplate more than one attachment "holding" a vessel (more than one parent). There is a workaround in SSV for the PRLA - RMS duo (which probably would not be possible with the SPSDK), but it won't work with the RMS and payload attached to something else, and it also won't work with another RMS and a payload in the PRLAs. It requires "cooperation" between the 2 parents holding (actually, trying to hold) the payload, and while that is trivial when the 2 parents are the same vessel, it is no so easy when there are 2 different parents.

So I am hoping some one can see what is wrong?
Launching of the LESAT Sat. Basically how I did for STS2016. It just add rotation and detach.

Ejection of the spacecraft from the Shuttle is initiated when locking pins at the four contact points are retracted. An explosive device then releases a spring that ejects the spacecraft in a "Frisbee" motion. This gives the satellite its separation velocity and gyroscopic stability during the 45-minute coast period between deployment and ignition of the perigee kick motor. The satellite separates from the Shuttle at a velocity of 1.6 feet per second and a spin rate of about two rpm.

if (spintable == 1) {
OBJHANDLE hChild3 = GetAttachmentStatus(sat_attach);
DetachChild(sat_attach, .2);
if (oapiIsVessel(hChild3)) {
VESSEL* vChild3 = oapiGetVesselInterface(hChild3);
VECTOR3 avel;
avel.data[1] = 0;
avel.data[0] = 0;
avel.data[2] = 12 * RAD;
vChild3->SetAngularVel(avel);
}
}
}

what happens is the SAT is launched but it should slowly rotate away

 

[GLS]

Could it be a pre-step vs post-step issue? Try moving that code to the other function (I don't know in which one you have it).

 

[gattispilot]

Yes that fixed it.
Thanks

 

[gattispilot]

Do we have specs for the Pallet? this is for STS51A

Search "Spacelab Payload Accommodation Handbook", and you'll find specs for the pallet and other parts of the SpaceLab system. The pallets were used as bases for other payloads, so those handbooks will only give info on the "basic pallet" without the extras that were mounted in them.

 

[gattispilot]

Thanks. Now just to figure where the trunnions fit

It should be on the 2 horizontal lines (the central ones) with the black dots.

Confused
I am trying to place a vessel in bay 10. I attach it in the scenario. but when I load it it is orbiting around the sun?
BASE_attach = CreateAttachment(true, _V(0, -.010, -0.02), _V(0, -1, 0), _V(0, 0, 1), "MMUFSS1", true);

then

not sure if attachment numbers are good.

 

[GLS]

I attach it in the scenario.

Are you editing the scenario?

After you add it in Mission Editor, does it show up in the PLB Preview?

 

[gattispilot]

I use the scn the mission editor creates. But i dont see the vessel. Going to play with it.
