Import Trajectories to Orbiter

[JohnW]

Hello!

Can anyone tell me if Orbiter offers the possibility of "switching off" the dynamics simulation and instead reproduce a trajectory (kinematics) provided through an external source?

I have generated a re-entry profile for a project through Matlab and I could probably manipulate it to any reference system and format.

What I am wondering is whether such an interface already exists, that is, if Orbiter can be used as a visualization and "further data" (like atmospheric density, etc.) analysis tool for a pre-existent trajectory.

I'd gratefuly appreciate if you could point me towards possible solution to this.

You can create a playback file for Orbiter from the data. The format is documented in the manuals and just a simple text file, you might just need to ensure that you use the right coordinate systems.

Quick answer - no.

Longer answer.... no but there might be other ways of doing this. What format is the data in?

Thanks for the quick reply. The data format would be "whichever you want". I set up my own simulator, so basically i can describe position velocity and acceleration with any discrete time-step found necessary.
Currently I have it with 0.5 second time-step in an ascii text file.

What I'll do now is to check out these manuals for playback data format Urwumpe recommended. Thanks.
