Are the IMU velocities equivalent to the GPS ground velocity, except for the coordinate reference system?
If the velocities measured by the IMU in the body-fixed reference frame are converted into earth fixed frame, are they equivalent to the ground velocity measured using the GPS?

How are IRUs and AHRSs different in terms of their functions?
By my understanding, both systems use gyros and accelerometers to provide aircraft's attitude and heading information. Given that the information they produce are more or less the same, why do the modern aircraft have them both? What are major…

How to make use of linear acceleration and gyroscope data?
This is strictly not aviation related so please feel free to move it to the correct section.
I have a 9 axis IMU, which gives me yaw, pitch, roll, magnetics, gyros, accels etc.
I currently make use of the roll, pitch and yaw (true) however I want to…

Does the Zenith have anything to do with the read-out of an IRU accelerometer?
Let's say that I have an accelerometer as part of an inertial reference system. Will the position of the Zenith with-respect-to the current position (in terms of rotation) of my accelerometer, have any impact on the accelerometer readings? Is there…
