Request High Level Architecture Interface for Orbiter

[tappm]

Hi,

I'm part of the SISO Smackdown technical committee regarding an international competition about modeling and simulation of NASA moon missions. This event is sponsored by NASA. In this context, I proposed connecting Orbiter with their existing simulations. This would require an HLA (High Level Architecture) network interface for Orbiter.

Pitch provides a very good HLA tutorial. They also provide a free community edition of their HLA implementation.

Games that provide an HLA interface include Microsoft Flight Simulator X, VBS2, X-Plane.

Do not hesitate to contact me for more information.

Thanks,

Martin

I could give it some reading this evening if a plug-in for Orbiter could be enough, AFAIR, HLA wasn't really complicated to implement and is not not require things that Orbiter can't do.

Do you work with CSA or are you independent?

Ok, back into the picture, what HLA was about... The hardest part would be rather bureaucracy, namely getting the Federate Object Model of your HLA federation mapped on Orbiters simulation model. There would be some more input needed in the forum to explain what you expect of Orbiter. Like for example, how you see Orbiters role there? and which RTI will you require?

As a Software Engineer, I run Warsim for the US Army, its an HLA simulation, You would need a multi-player server application, and a client application. We have a multi federate participation, once the threads are established, running the sim for a period works well, and clients may engage and interact with the server at any time. The server in our sim needs down time for clearing the Oracle database it rides on, but this is not unusual for an accumulation style simulation where After Action Reports are gatherd and evaluated.

I don't know what they are looking for but this sounds very interesting to me, from a HLA Sim Software Engineers point of view. I'll monitor with baited breath.

Hi,

thanks for the feedback and interest!

@BruceJohnJennerLawso: I work for CAE Inc in the training device industry (particularly that of aircraft simulators both civl and military).

@Urwumpe: I expect that the federate object model used is based around RPR 2.0+. This basically involves mapping Orbiter's vehicle states to their corresponding Platform class derivative, such as Spacecraft for instance. The documentation, i.e. RPR GRIM, is available here.

As for Orbiter's role, it would be to publish and subscribe mainly to any platform it can map to in order to allow interactions with, mainly, spacecrafts.

On the RTI side, Pitch's free one which I mentioned can be used (HLA 1516 2010 i.e. HLA Evolved).

Martin
