Shuttle FDO MFD

Another small update, the full list of emergency landing sites is now also available for the deorbit opportunities and not just the deorbit maneuver processor:

Hi, I installed FDO-MFD in Orbiter's folder and how can I open it in SSV? I can't see any enable option...

Did you enable it in the Modules tab in the Launchpad?
 
Is the ShuttleFDOMFD.dll file in the Modules\Plugin folder?
Is so, can you check the Orbiter.log file? There should be a message there....
 
You probably didn't download the final product, but instead downloaded the source code. Click in the Releases link on the lower right of the page. The latest release (for Orbiter 2016) should still work in Orbiter 2024.
 
Yeah I had a bit of trouble getting the MFD to build in Orbiter 2024, but that is mostly resolved now. I also don't like that I can't use debug mode with Orbiter 2024...

But I will do a dedicated release of the MFD for 2024 soon. I guess I should also finally change the example rendezvous scenario from SSU to SSV, I don't think anybody is going to be mad about that :D
 
Hi, I am new to SSV (never used SSU - only default Atlantis to randez-vous ISS) but created a custom mission and scenario with better ISS. Found good launch window in 2025 - needed to copy ISS position from another scenario. As I read about FDOMFD I don't understand from which file it gets data about my ISS. Mission or scenario? It is all a bit overwhelming but I really want to grasp it :)

On the configuration page of the MFD you tell it the names of the chaser (Shuttle) and target (ISS) vessels. When running any on-orbit rendezvous calculation with the OMP it will then take the state vectors from the Orbiter API.
 
Here is the promised release for Orbiter 2024. No real changes to the MFD. I just made it buildable for Orbiter2024, switched to VS 2022 and removed the tutorial scenario for SSU. I had actually made some changes to the STS-126 launch scenario that comes with SSV a while ago and that scenario is perfectly useable for the OMP walkthrough, which is now mentioned in the manual.

Hi, with FDO I managed to deorbit and land at KSC easily:) My attempt to RV ISS ended at some 2000m to ISS after last burn. Is it OK?

With the last burn you mean what, MC4? I have never actually done these burns with the FDO MFD, the final few maneuvers are targeted onboard.
 
New release:

Fix bugs related to the changed gravity model in Orbiter 2024. Due to the way the MFD was getting non-spherical gravity parameters from the Orbiter API some code of mine went from "bad, but it works fine" to "at best it is inaccurate, at worst it uses uninitialized memory and it has a random chance of not giving a solution at all". This would show up when using the MFD in non-spherical gravity mode and then probably in all features of the MFD (OMP, DOPS, DMP). Random chance of calculations not working right. Now instead of getting parameters from the Orbiter API there is a hardcoded gravity model that the coast integrator in the MFD uses. So it should now work the same as in Orbiter 2016 again!
