Using ScnEditor module you can place some ship to any orbit and target it.

BTW, You can combine patched conics approximation with more precise GMAT propagator. For example, part of some my old script: lambert_v1 is a user function (in /userfunctions/python/PyKEP.py):

My understanding is that if you vary two different parameters, for example delta-v between 2000 m/s and 3000 m/s and time between 10 s and 20 s using "Additive scale factor" and "Multiplicative scale factor" you can manually normalize both variables for the solver to vary them internally, for...

If I'm not mistaken NASA’s Eyes software uses such textures. Once I tried to extract a texture of some moon from NASA’s Eyes to use it with Orbiter and it was a bummer ;)

It depends on model. With GRGM900C GMAT shows even a bit slower orbit degrade rate with the same 120th order/degree:

Looks close:

Looks good. Can you give the scenario file or just initial MJD/RPOS/RVEL? I want to compare this with GMAT. That's how it looks in GMAT (using LP-165 model) for arbitrary MJD:

How did you implement this changes? I thought about making minimal changes to the Orbiter core, just interfacing GetPertAcc() to celbody modules through a CELBODY class extension. But I'm not very good with C++ to propose my changes to the Orbiter core.

I'd like to see CELBODY API extensions for rotation (to be able to implement IAU / ITRF frames) and for gravity fields (to implement EGM96, GRGM900C, etc.)

Is something wrong with my Orbiter config? Or it's a D3D9Client issue? Scenarios\Delta-glider\Brighton Beach.scn:

I think he meant https://github.com/orbitersim/orbiter/actions/runs/2989073829

That may be useful too: https://ssd.jpl.nasa.gov/tools/periodic_orbits.html#/periodic

There are scenarios for Orbiter. No addons are required, it's just DeltaGlider + Artemis-1 POS/VEL from the latest preflight data ( https://ssd.jpl.nasa.gov/horizons/app.html#/ )

o_O OMG, and it's nasaspaceflight.com

Yes, it will be interesting. I wonder how close the trajectory will be to my GMAT NRHO computations https://www.orbiter-forum.com/threads/lop-g-to-brighton-beach-and-back-again.36984/#post-556247

Yes, of course. And the ship will be accelerating slower and slower according to an external observer at this destination.

Faster relative to what? If you're measuring your speed/position relative to the position where you would have been without acceleration, then you are assuming that yours v0 a second ago was 0 m/s, not 0.9c. If you're an external observer who's observing some crazy spaceman flying around at...

You can compare your calculations with https://www.omnicalculator.com/physics/space-travel

This article may be helpful: https://en.wikipedia.org/wiki/Space_travel_under_constant_acceleration And don't forget that you can compare clocks of two observers only in the same space-time point, so you can calculate "how much time passes for each observer" only when they meet again after first...

I can confirm that it works.
