May i know which files do you use for a simulation through the paparazzi center? I mean which xmls are used?

mundhra,Im using the Tiny 2, but the hardware doesnt matter, functionally they are the same. I wrote my own filter(actually quite simple) to do the attitude estimation by fusing the accel and gyro data. There is a much better example in the CVS in the sw/airborne/booz folder of a proper AHRS which uses IMU data. Not sure why you would want to get rid of IR for a fixed wing application, but I guess if you are trying to fly indoors an IMU is probably your best bet.AJ-------- Original Message --------

To: address@hidden, address@hiddenwith which Autopilot have you used the Sparkfun IMU? Is it tiny 1 or tiny 2? What software modifications did you do for that? Is it working fine? I mean are you getting the correct attitude estimation without using the IR sensors?

I've used an 6 DOF IMU from SparkFun with no software problems.
only use analog signals instead of IR's.
