Don't forget to check the box Parameters > Perturbations > Nonspherical gravity sources (because Sun-synchronous orbits are permitted by the fact that Mars, like Earth, is not spherical)

what plugin? where?

Small information, good news: my sponsor (i.e. my employer...) just renewed its support and confidence in Nex'Orbiter experiment. We'll open the website in a few weeks to tell just-a-little-more about the gameplay, that you could also influence with contributions... In the meantime, let's...

It would be of course nice to use Orbiter for your work. Nevertheless, you can also use another free visualization tool, that makes use of Celestia as a graphic engine: VTS by the French space agency CNES, that also has a stream feature (to display on the fly...). All data need to be formatted...

Hi, I think there is a confusion here: MJD is just a format, TDB is a time system. SPICE uses a reliable conversion between common time systems (TDB, UTC, TT...) whereas UTC is the time system apparently used by Orbiter. I know it sounds weird but Earth time system (UTC = Orbiter) is quiet...

many interesting avises here, thank you, Face I guess I can re-code a server in C++ (not C#) using .NET (5+, because <5 not supported after VS2019) and still compile to Linux tagets, can't I? (unless I use Windows' GUI... but if terminal only it should work in Linux)

What about PostgreSQL linked to C++ server with libpqxx... would also pave the way to mulitple (Linux or Windows) servers in redondance...

Now OMX is super-easy to install: just unzip into a vanilla Orbiter 2016 (to avoid conflicts) and accept all replacements. Reminder: OMX will remain a GPLv2 engine. It supports a persistent universe (i.e. deep space, saving states, continuous propulsion, life support, cooperation). It does not...

20 years in aerospace industry, then 10+ years as an astrophysicist, pushing nanosatellite era for science... less money but more fun :)

And that's fine as it is, IMO. in OMX, I don't use this management anymore, see rather STC_Vessels.cpp in the 1.1.0 release. My approach is to only save what I need to transfer and nothing more. In particular thrusters and fuel when a client needs to TRANSFER its vessel to another client, then...

niiiiiice ! I can see 3 docking ports in the "hotel" and 4 in the "lifehab" (that is, I guess, at the center)... On the pic I can only see 2 free docking ports, correct? Could you start from the wheel station and make, say, 36 available peripheral docking ports (1 every 10 deg.), in addition of...

/MT is Multithread /MD is DLL multithread => what's the difference?! I always use /MD(+debug) but maybe I do a mistake...

Nice resource!! I think these 3 pics in particular explain a lot (the 2 first ones look contradictory to me):

\begin{matrix} \overrightarrow z &= \text{thrust vector} \\ \overrightarrow y &= \text{top} \\ \overrightarrow x &= \text{left wing}\\ \end{matrix} for instance, or \begin{matrix} \overrightarrow z &= \text{thrust vector} \\ \overrightarrow y &= \text{bottom} \\ \overrightarrow x &=...

Not sure if it helps, but I see a lot of risks of misunderstanding... just to make sure we talk the same (mathematical) language, I stress out that: 1°) your matrix R allows to compute the equatorial coordinates of a local vector (horizon frame, with Z = zenith or anti-nadir): \overrightarrow...

Hence, a HUD similar to DeltaGlider's HUD would make a lot of sense

Nice interior! However, in my understanding/memories, Eagles' views to outside would rather be a hemispherical glass in 2 halves (left and right) offering a large field of view (90°x90° left and 90°x90° right), than 2 flat tiny windows, aren't they?

make sure you killed all thrusters, a small residual in hoover for instance, will prevent from keeping landed.

You need to call this piece of code at each frame (in ocpPreStep/opcPostStep or clbkPreStep/clbkPostStep). In OMX it's more complicated, but same concept, I do a loop on all vessels of the simulation, I simplified here below for you, removing all OMX specificities: OBJHANDLE handle...

It looks really cool! I especially like the reflection on the helmet. so, the hab was finally transferred :)
