Hi Tom,
I made the comparison between the angles obtained with accelerometers and those obtained with the gyros. The difference is quite large, with an accelerometer get 30 degrees (real angle) and the gyroscope -150 °. Modify gyrobias bits, changing bit more influential, but all I get is to decrease the angle obtained from the gyroscope to -100 °.
The modification of the bit carried generating random numbers in an interval containing the initial gyrobias, met with the gyroscope free motion.
I wanted to ask if you only had the gyros IDG-500, which would be the way to get the bias for each gyro, for different angles roll, pitch and yaw.
