We develop Dead Reckoning system for series manufacture and now we are looking
for sensors for this system.
We plan to use low cost sensors like ADXRS652 or ADXRS623.
Unfortunately datasheets for these gyros do not contain some key performance
parameters that play major role to DR system accuracy.
Could you detail the following parameters for specified gyros?
1.Typical  and max values of “In run bias stability”
2.Min and max values of “Rate noise density”


We have the rate noise density (typical) listed in the specifications table and
an allan deviation plot is included as part of the performance charts.  You can
calculate the in-run bias stability from this plot. However, since neither of
these parameters are tested in production, we are not able to guarantee a max
