Mathias Froelich and myself are the best people to ask about this.  I'm
happy for you to contact me directly via this email address, and I will
contact Mathias on your behalf (he does not monitor this list and is
currently engaged on another project, so may not be available).

My availability is limited over the next couple of weeks due to holidays
etc, but I will do my best to answer your questions.  I'm also actively
developing improvements to the FlightGear HLA support, so would be very
interested in discussing possibilities with you.

To answer your specific question:  From memory the orientation is the
(i,j,k) values for a quaternion in ECEF.  I'm about to head away until
Monday night, but will double-check on my return after Easter.
