This programs subscribes to 'AHRS_STATE' messages. it converts to flight gear
FGNetGUI format and send them to it.
I used it to make this video :

launch it and have some device send AHRS_STATE messages on the bus
the makefile in sw/logalizer contains exmaple on the command line used to launch
flight gear

this is not exactly what you want but close.. the simulator can send to
flightgear. Use the -fg option to specify the address of the machine runnning
flight gear

For what you want to do, you could write a little agent similar to ahrs2fg
It would subscribe to ATTITUDE and GPS messages, convert those data to
flightgear format and send to flightgear. This way, simulator, real aircrafts
and replay could be displayed in flight gear

good luck
