Re: [Flightgear-devel] Aircraft state values

[Noah Brickman]

You mentioned outputing data to a socket. Can you give me an outline of how
to set that up? Doing everything is JSBSim is fine for now. I think I just
need aircraft orientation and g-forces on the pilot.

Subject: Re: [Flightgear-devel] Aircraft state values

 I'm attempting to assemble a list of basic aircraft state values, like
yaw,
 pitch, roll, and velocity and acceleration vectors. I'll probably be using
 the JSBSim FDM. Is there a place where this information can be easily
 extracted from the program? The FGState::ReportState function seems to
 assemble some of this info but it has been commented out due to use of
 depreciated functions.
 
 Thanks,

Hi, Noah:

As for extracting data, do you want to push, or pull? JSBSim (like
FlightGear and it's parts) is very configurable. If you want to output to a
file or through a socket, that can be done easily. If you want to extract
values at runtime programmatically, that can be done as well. If you can
elaborate I can help you more.

Re: [Flightgear-devel] Aircraft state values

[Jon S. Berndt]

 I'm going to be connecting flightgear to a motion platform, propably
 through
 UDP. I'll need at a minimum yaw, pitch, roll for the aircraft and g-
 forces
 that the pilot is subject to. If this could be done in a FDM-
 independent
 manner that would be nice but isn't necessary. I don't know how the
 motion
 platform needs this packaged yet. Logging to a file would be an
 acceptable
 first step.
 
 On a separate note, I'll also be attaching an Intersense 3-dof motion
 tracker to control the pilot's viewpoint. Suggestions on that would be
 helpful too.

If you need it to be FDM independent, you would want to use FlightGear's
loggin capability. I'm not familiar with that. Someone else here can surely
comment on that.
