I have studied Kalman Filtering with respect to inertial navigation for quite some time. I look into the ArduPilot code and I see that it allows for an EKF to run on a per-IMU basis, and can choose the one that's best suited for navigation. …
"The dynamic that makes the IMU + GPS EKF work is that the GPS error is constant over time, and the IMU positional error grows (from zero) with time. The current state of mems IMUs today is probably such that it's unwise to allow it such "freedom"…"
"The difficulty is the fusion of sensors. It's easy to make a navigation system with GPS telling you where you are, but the moment you start judging your position based upon other sensors, you start accumulating error. Allow me to lend you an…"
"First post here :) Allow me to give my qualifications. I was a WSN-5 tech in the US Navy. Since then, I've studied inertial navigations as a hobby.
