Hello Mr. Ristic,
I would like to appreciate the succinct description of sensor fusion provided in the aforesaid article. But, while working on sensor fusion for the the estimation of velocity of a body frame, I came across some real world challenges, for which I seek advice.
*When the mobile device is mounted on a moving body frame, there are 3 coordinate systems, the geomagnetic earth frame, the frame of device mount and the frame of motion of the body itself. In this case, how can we project, the acceleration vector on to the body frame only?
*Furthermore, from inertial navigation, we can use gyroscopes to lock in inertial vectors in the reference frame. But, how do we account for centripetal forces in this case?
It would be really helpful if the doubts enumerated above could be clarified.
The author has to be congratulated for an excellent article on sensor fusion and its future directions.
I also would like to call his attention (since he is local to Silicon Valley) to the event on a closely related topic being held on a Saturday this month (29th):
Next Generation Circuit & Systems, Communication and Sensor Technologies in Mobile Devices
NASA's Orion Flight Software Production Systems Manager Darrel G. Raines joins Planet Analog Editor Steve Taranovich and Embedded.com Editor Max Maxfield to talk about embedded flight software used in Orion Spacecraft, part of NASA's Mars mission. Live radio show and live chat. Get your questions ready.
