    [NASSP 8][Apollo 8] Realtime simulation preparation

    Not a typo in NASSP, the switch says LM/CSM. Must be a typo in your source. The switch affects the behavior of the SCS Auto TVC. It is set to LM/CSM for launch, at least for heavy CSMs, for the following reason given in the AOH Volume 2: "Provides reduced gain for SPS thumbwheel control of SCS...

    Apollo 17 Launch Time Change and Azimuth Update Steps

    The only way to do it right now is to edit the T-4h scenario. Find the line: MISSNTIME -14400 That is minus 4 hours of mission time. There was a delay of exactly 2:40h, so you need to change that to. MISSNTIME -24000 if my math is correct there. Sadly we can't do "in-sim" countdown holds and...

    Apollo 16 LOPC-2 and Shape Questions

    No that is LOPC-1. LOPC-2 is after rendezvous and getting rid of the LM. But targeting wise it should be very similar. "The CSM performs a second plane change on rev 61 to increase lunar surface photography coverage." What I did when flying Apollo 12, which also did a LOPC-2 for photography...

    Shuttle FDO MFD

    Someone from the (former) SSU team can probably answer this better, I can't really remember. I actually played around with the code for this and I might have implemented roll angle of 0 just in my local copy, but it never got to a stage where I would have called it good to be integrated into...

    Apollo 11 MCC LOI-2 doesn't print.

    Ah sorry about that. A few days ago someone flying Apollo 12 tried to use mode 6 (powered descent simulation) of the Lunar Descent Planning Processor (LDPP), which is not available yet and it overwrote the time of landing with NaN, which was a bit difficult to revert without scenario editing. So...

    Apollo 8 - NASSP v1858 - optics issues or my mistakes?

    As it turns out, this is incorrect. For Apollo 14 they added a new program to the CMC, Program 24, Rate-aided optics. In that program, and in that program only, is the CMC allowed to drive the optics in manual mode. It helps the fact that sometimes you have to command fairly large optics rates...

    Problem Couple of problems with NASSP

    Yeah the optics zero switch can catch you out. After a period of having optics powered off you also need to cycle the switch from zero to off to zero so that the CMC knows that it's being zeroed. And it is possible (but unlikely) that the real position of the optics (shaft and trunnion angles)...

    Apollo 8 - NASSP v1858 - optics issues or my mistakes?

    There is multiple things going on here. The optics system of course has limits in trunnion and shaft angles, so it's normal that you can't move it beyond a certain point. I'm starting to think this is a bad idea. I have conflicting information about what they intended to do on the actual...

    Problem Couple of problems with NASSP

    A video might help yeah. But you did say you are getting a program alarm (PROG light goes on) at some point. When you check V05 N09, what is the alarm code? And at what point in the procedure do you get the alarm?

    Problem Couple of problems with NASSP

    How is the state vector after insertion this time? V82 showing goods things? I am pretty sure you are doing something not quite correct after getting the 405 program alarm, because in your T+38min scenario P52 worked perfectly fine. So let's take it step by step. You are getting to the step in...

    V8 Release Work Thread

    The Apollo 7 MCC has been reorganized a bit. Sadly I had to break old scenarios for that. The mission scenarios that come with NASSP have of course been fixed and if you have just launched, scenarios saved before the first state vector uplink at T+56min are also fine. Otherwise I would suggest...

    Problem Couple of problems with NASSP

    As I said getting that 405 program alarm in P52 can be quite normal even if you did nothing wrong, just some bad luck with star availability at the time. Aside from the state vector being off I can't seen anything wrong in the scenario you posted. P52 works as expected. "Apollo 7 launch", do...

    Problem Couple of problems with NASSP

    Ok the CMC state vector is indeed bad somehow. No idea why yet, but the uplink later would fix that. You did let it uplink the state vector at T+56min, right? That could tie into the next issue. The CMC checks if the Earth is in the way of stars or if the star is within 5° of the horizon. And...

    Problem Couple of problems with NASSP

    That is probably caused by RCS firing. Time acceleration doesn't go well together with any vehicle trying to fire thrusters. When you are still attached to the S-IVB then the S-IVB will perform the attitude control. With that you can safely use 10x, but I don't think more. After getting away...

    Question Apollo 7 launch - abort mode 1

    Aha! The NASSP releases do have a file that belongs in there that you for some reason don't have or don't have anymore. So just check in the last NASSP release for the 001131.elv file and put it in there. That should do it.

    Ok, what do you have in Textures\Earth\Elev_mod?

    Question Apollo 7 launch - abort mode 1

    Ah, I can reproduce it now. The terrain near launch complex 34 is not level in Orbiter. That's why NASSP comes with a modified elevation file to make the launchpads we use in NASSP completely flat. If I delete that file then at launch the orientation of the Saturn IB (using the T-60s scenario)...

    Question Apollo 7 launch - abort mode 1

    That seems to be a dip down to 40 fps, which should be ok I would think. Is your Saturn IB slanted, so not pointing straight up? Also, just to confirm it again, this happens every time in every Apollo 7 scenario with you, is that correct? The T-60s scenario provided with NASSP does also cause...

    Question Apollo 7 launch - abort mode 1

    Hmm, so then it seems like you somehow get a big attitude rate for a short moment at liftoff. Can you confirm that on the FDAI rate needles? Is it only at liftoff and then settles down? Do you get a bad framerate at liftoff? Maybe it's related to that. Does it also auto abort if you look at the...

    Question Apollo 7 launch - abort mode 1

    So you are getting an automatic abort. Does it happen right at liftoff? There is only 3 conditions that can really cause it. A sudden high attitude rate, loosing two or more engines or the connection to the IU breaking up (EDS buses loosing power). High attitude rate or loosing engines right...
