I've been experimenting with the OMS extensively trying to perfect a Reentry scenario for SSU. I've run the same scenario (and stock reentry scenario's) over and over without any time compression involved and the TFF reading varies considerably post burn. I've seen gaps of over a minute in some cases resulting in shorting dangerously on reentry.


1. Would the TFF be identical in the real shuttle if you ran the same burn over and over?

2. Is it that the OMS in SSU is still in work and has anomalies in the burn or the timing?

1) I'd think so (plus or minus a few seconds maybe)

2) The OMS needs work (but currently is not in development), but they start and stop OK, so it doesn't make a difference. Now, the math that decides when the burn takes place, how long it is and in which direction it should go... that almost certaintly needs work.

On the TTF thing, my money is on the state propagation (used to get that time) not being 100% correct and/or Sun/Moon perturbations changing the orbit. There is also some variations in the target Ap and Pe values shown in the MNVR display during the OMS burns.

Thanks it's been driving me mad. The Ap and Pe values I see change a lot but don't seem to affect the outcome. However I've noticed the OMS light up a second too early also on occasion also. The TFF thing has been screwing over my timings for a sequencial sound pack to go with my scenario but I'll use a workaround now I know it varies beyond my control.

Just an extra to save me asking elsewhere is there an svn checkout link for the version to go with 2016 or is it still under wraps?

All the stuff is in svn. The 2016 version (still incomplete) is in the OrbitersimBeta branch.

Could you give me the correct link for svn 2016 version please? The ones I try keep giving me error messages user error most likely of course. I imagine it's simple but clueless here.

Whether state propagation plays a role could be easily checked by running with fixed time steps. This should make the state propagation reproducible. If you still see variations, they would have a different cause.

Also keep in mind that the upper atmosphere model in Orbiter has daily and seasonal variations in temperature and density. Although that shouldn't matter if you always run the same scenario with a fixed start date.

The state propagation that I'm referring to is internal to SSU, don't worry. :lol: It's used for OMS burns targeting and to calculate time to apogee and perigee, and also the time to 400Kft.
 
Off topic but ...

Off topic but didn't want to start another thread. I'm compiling using 2010 and getting the following.

You need to install D3D9.
 
The state propagation that I'm referring to is internal to SSU, don't worry. :lol: It's used for OMS burns targeting and to calculate time to apogee and perigee, and also the time to 400Kft.

Also, AFAIR, we are not using Kalman-Filtering there, so we likely have a much bigger error than the real one.
 
1. So can/will this be refined at all?

I am optimistic. But remember, SSU is a huge work in progress, we will sure never run out of things that are not yet working or working well.
