Hi Brooke,

Looks like the physorg paper is talking about an optical rate gyro.
Don't think the drift rate matters, since position is not measured.

Yes, your reference gives bad numbers for a fiber optic rate gyro,
but the physorg paper claims a device that works.

Something is out of joint. (Thin reference to time in Hamlet)

Hi Gerald:

It turns out the the long term drift spec of a gyro depends (using a 
large power law, far from linear) on it's volume.  See:
I expect that one that can fit into the head of a pin will drift much 
more than 1000 deg/hour.

Have Fun,

Brooke Clarke
