I reccomend reading this first

Cooke, Zyda, Pratt, and McGhee, 
"NPSNET: Flight Simulation Dynamic Modeling Using Quaternions", 
Vol. 1, No. 4, pp. 404-420 Naval Postgraduate School, January 1994 
http://www.npsnet.org/~zyda/pubs/Presence.1.4.pdf

then looking at the code in JSBSim as Jon suggested


>From the JSBSim code base see:

>FGState.cpp
>FGPosition.cpp
