I am wondering if a DSP specific device would provide the same or better bang for the buck? Most of the sensor processing is the filter and that should be implemented very well with a DSP type of controller chip (possibly lower cost as well). Having worked on navigation systems using only accelerometers, gyros, wheel encoders I can say there are many sources of error. The greatest is external forces that exceed the sensors operating range (read here: 3g bump with a 2g sensor). Frequency response, sampling rates(and sampling rate errors), sample errors all contribute to the overall system error. Yes the Kalman filter will help significantly but there are limits.

I wonder what's responsible for the pronounced bias in the error?

This was an informative article. Maybe EETimes can find a way to host more master project descriptions. Anyone else think that's a good idea?
