Dear Shay,

    Thank you for your response.I've learned of the
Allan Variance Method used to calculate the angular
random walk(ARW).But how to understand the following
sentence?
     'The noise equivalent rate is 470deg/h in a 60 Hz
bandwidth,equivalent to 0.02deg/s in a 1 Hz bandwidth
or angle random walk of 0.72deg/sqrt(h).' From
'Micromathined Inertial Sensors' by NAVID YAZDI,
FARROKH AYAZI, AND KHALIL NAJAFI.IEEE proceedings
1998.

     Is there a conversion method or it's just device
specific(that is ,the data is just coincidence.We
can't get the ARW from expression like '470deg/h in a
60 Hz bandwidth')?

Sincerely yours,
Matthew King
