Displacement path of object based on accelerometer records

Hi to all!

I have a rigid body equipped with two accelerometers.

The accelerometers record along local axes and by double integration of accelerations i can obtain displacements along these axes.

I want to retrace the actual displacement of the object by a global (fixed) reference system, but the reference systems displaces with the body and ROTATES, so I should account for the different orientation of axes during analysis.

Any idea of which procedure to follow to track the body global displacements?

What rotation data do you have? You need that in order to resolve the accelerations in the global fixed frame.
