    V8 Release Work Thread

    A reconstruction of Comanche 72 revision 3 is now available! So Apollo 13 in NASSP now uses the correct software for both CMC and LGC. Thanks again to @thewonderidiot for accomplishing this difficult feat. Going further than this is not really possible as Comanche 108 for Apollo 14 had too many...

    V8 Release Work Thread

    As it turns out the Comanche 72 reconstruction might be a bit tricky. I also discovered that, due to the small number of differences between Comanche 67 and 72, old scenarios using Comanche 67 would not break when changing to Comanche 72 in the middle of a mission. You could just be in P00 and...

    NASSP 8 Installation Guide

    I think you have a DX9 Client for Orbiter 2016 installed instead of for the Beta. Here is a difference between our Orbiter logs: Yours: Module D3D9Client.dll ........ [Build 211009, API 160828] Mine: Module D3D9Client.dll ........ [Build 210722, API 190914]

    V8 Release Work Thread

    He has done it again! Now available in NASSP is Comanche 67, the CMC software flown on Apollo 12. The software comes from the flight spare rope modules and was read by @thewonderidiot with his rope reader, as before for the Skylark modules and others. There is only one major update from the...

    Deorbit Planning Table for Orbiter 2010

    I didn't know there was still a demand for an Orbiter 2010 release, so I hadn't created one. Here it is now: https://github.com/indy91/Shuttle-FDO-MFD/releases/download/0.4.0-alpha-O2010/ShuttleFDOMFD_O2010_0.4.0.zip

    V8 Release Work Thread

    To enhance the latest Virtual Cockpit update even further, a new type of rotational switch class has been implemented to allow lighting controls (and some others) to work more like the potentiometers they were and have finer control over them: As you might be able to tell from the video...

    V8 Release Work Thread

    @Jordan has done some more wonderful work and given our Virtual Cockpits in CSM and LM more upgrades. A few small things here and there, but the huge new feature is the lighting controls (flood, integral, numerics) are now working. I think this is best demonstrated in a short video: Enjoy!

    Shuttle FDO MFD

    ADD button on the maneuver constraints table. Have you checked the manual? It also has a walkthrough, although that was still written with SSU. Most of it should still apply with SSV.

    Shuttle FDO MFD

    Could you be a bit more specific? Are you asking how to calculate the burn with the FDO MFD? That should be covered in the manual. Any more specific question, feel free to ask them here!

    Orbiter Video Thread

    Two videos about the recently recovered Skylark 48 AGC software, which was used on the Skylab missions and ASTP. First a video about the whole sequence of rendezvous maneuvers, with some docked attitude maneuvering at the end as a bonus. And then a video based on the Skylab SPS Deorbit...

    Apollo 12 LM AGC STBY

    We have finally found the cause of the standby mode bug and it is now fixed in the latest NASSP release!

    Apollo 12 LM AGC STBY

    It might not have been something you did wrong, just, in some circumstances the LM can rotate in yaw while sitting on the surface in Orbiter, while in reality that of course didn't happen. That said, I only see the technique 3 (Gravity + Celestial Body) in the checklist and I don't think the...

    Apollo 12 LM AGC STBY

    Your IMU alignment is off by 6°. But only in one axis, yaw. I think I have seen this before. Did you use the "REFSMMAT + gravity" option in P57 at all? What can happen is this. You do a P57 using any other technique and the LGC saves your yaw angle sitting on the surface. Then an Orbiter-only...

    Apollo 12 LM AGC STBY

    The LGC clock didn't update properly, so very likely, when you are doing the lunar ascent, the clock is still many hours off and that is responsible for the LGC not finding the CSM. There are two possible things going on. The AGC has a time limit for how long it can stay in standby mode and...

    V8 Release Work Thread

    Another big update! Our S-IVB now simulates propulsive venting. All the time during Earth parking orbit Saturn V S-IVBs vent a little bit of their H2 to keep the tank pressure down while it is heating up. While there are non-propulsive (NPV) venting valves as well, during Earth orbit coast this...

    Apollo 9 LM Landing and Rendezvous Radar self-test error???

    They rearranged the verbs some time between Apollo 9 and 10. So it's a bit different in Sundance (Apollo 9 LGC software) than all later versions. I tracked it down to program change request (PCR) 420.2: This was implemented in Luminary 31, some time in mid 1968. Apollo 10 flew Luminary 69...

    AGS vs PNGS Rate of descent disagree on low altitude Descent Abort

    Yeah I added a way to show the misalignment of an IMU, but don't use it to get V42 angles, that is cheating! :D I mainly added it so I could quickly check in scenarios how good the alignment is, for troubleshooting. Otherwise I would have to do a full P52 just to check. It might also be useful...

    AGS vs PNGS Rate of descent disagree on low altitude Descent Abort

    State vector uplinks to the AGC are using Ground Elapsed Time, so the RTCC needs to know the exact time when the AGC had its clock zeroed so that it can convert an "absolute" time to GET for the uplink. That's all this little 0.26 second update in the RTCC does, so that it knows exactly what GET...

    AGS vs PNGS Rate of descent disagree on low altitude Descent Abort

    There are a few things I notice in your scenario: -The current GET is very different from the flight plan time for PDI. I guess you are simulating the actual mission with its delay? Should be no problem to do that. -The RTCC liftoff time wasn't synced to the CMC liftoff time. This is a fairly...

    Project Space Shuttle Vessel

    The result looks a bit strange. It seems like the OMS-1 PEG-4 target transferred properly to I-load, but not the insertion targets or the OMS-2 PEG-4 targets. The OMS-2 PEG-4 values are the default ones, maybe that insertion orbit is, too, looks a lot like a direct insertion for a ground-up...
