Hello friends!
I want to know that data of IMU belongs to which frame means weather it belongs to inertial frame or body frame?
Huh ? While I can understand that English is not your primary language, it's the one I speak and the above is mostly gibberish in it. What IMU ? What data ? Relying on a strict interpretation of the word "raw", that's always in the frame of the IMU, the frame in which the measurements are being made. That frame is usually tied via a constant rotation matrix to a vehicle "body" frame, though sometimes the 2 coincide.narayan:

The inertial reference frame is one that doesn’t change and is commonly one of a few Earth-centric frames that allow easy interpretation of the data. NED (North, East and Down for X, Y and Z axes) with the origin (X=Y=Z=0) to be the initial location of the IMU is a common inertial reference frame. Measurements taken by the IMU in it’s frame can be translated into orientation and translation (position) of the IMU (and therefore the body as well) in the inertial reference frame. Inertial navigation is the process of doing this continuously over time so as to maintain a record of those orientations and positions.
