Does anyone know how to model error in gimbal system axis?

09 November 2012 1 2K Report

The navigation system can measure the attitude (EULER ANGLES) through 2 technologies, strap-down and gimbal systems.

If the gimbal axis is not aligned with the "inertial axis (because some reason) , how can I model the error at that case? How will be the Euler angles sensed by my sensor? I know that the two system the inertial and gimbal axis( which is inertial fixed) are related by a direct cossine matrix.

But how can I calculate the difference between the true euler angles(inertial axis) and false angle that you suppose it was aligned with inertial axis but it's not.

You induce uncertainty in all three axes and test the results using a MonteCarlo sim
