"Tom,
Could you suggest a way forward to try JSBSim as a atand-alone simulation tool. I am completely new to the package.
Thanks in advance.
Regards,
Akshay"

Faisal Shah commented on Kirill's blog post OpenPilot Open Souce UAV Platform"I'm a big fan of DIYDrones, as well as OpenPilot. Both are fantabulastic projects. I am a little worried though about the negative attitude of OpenPilot towards DIYDrones. They claim that DIYDrones used some of the design from OpenPilot (which…"

Update: I have switched my generic format profiles from ASCII string format to binary and the lockup on startup problems have gone away.

Mike Inman replied to Faisal Shah's discussion Using flight gear to test autopilot algorithm"Hey,
Thanks for posting your example. I am trying to do something almost identical using FlightGear 2.0.0, but, the program hangs during "loading scenery objects" on the splash screen, unless/until I have an active control loop running.…"

It was very concerning of me to read the following:

Closed loop autopilot simulation with FlightGear - Part 2

Figured out how to close the loop!
Programs can interface with FlightGear through FlightGear's property tree. Very powerful.
http://wiki.flightgear.org/index.php/Property_Tree
If you run FlightGear with the --httpd= option, it will run a webserver on http://localhost: where you can browse the property tree and refresh the current values. Alternatively, in FlightGear you can type "/", and the property… Continue

Closed loop autopilot simulation with FlightGear - Part 1
Posted on October 19, 2009 at 10:30pm 2 Comments 2 Likes
I don't have the cash right now to buy a plane, ArduIMU, an auto pilot, and associated hardware. So, while I'm saving for the hardware, I want to play with the various algorithms out there in a simulation environment - to gain a deeper understanding and feel for it. I want to be able to code in C, so I can use the code directly in the hardware autopilot when I reach that point.
I want to use a flight dynamics model to generate sensor inputs to the autopilot (3 axis gyro, 3 axis… Continue
