Interesting idea. Not sure how they're going to disentangle the usual rolling, pitching, and yawing on a ship with straightforward level motion.
I guess you could contrive some kind of gimbal suspension, but that's not going to be friction-free so there will be cumulative inaccuracies.
- AndrewDucker 3y agoNot sure you'd need to disentangle it. Any given millisecond you'd move forward+up, forward+down, forward+port, forward+starbaord. Add them all up and you'd known that you'd mostly gone forward.
- moffkalast 3y agoYeah it's kind of like summing gyroscope values at a constant rate, it just cancels out and gives a good rotation with a little drift over time. If only regular accelerometers were as good as mems gyros.
- dr_orpheus 3y agoNo need to disentangle it. You would be integrating the linear motion with the accelerometer they are developing and use it with a gyroscope that measures the rotational motion. Then the full 6 degrees of freedom are measured. We already have very good gyroscopes that measure rotational motion (such as Fiber-optic gyros [0]) with really high stability.
