Well, that, and there's no such thing as a "solid state laser gyro". I believe the GP is confusing MEMS solid-state gyros and laser-ring gyros (which can use a solid state laser, but AFAIK aren't ever called "solid state laser gyro").

MEMS gyros have too much bias drift (both on a unit basis due to fab processes and on a temperature basis) to be practically useful here. You can measure the earth's rotation with a MEMS gyro, but you're really at the limit.

Heh, while I get what you're saying... despite being somewhat pedantic... there are in fact MEMS FOGs now too :). https://www.anellophotonics.com/technology

Laser ring gyros are referred to as solid state laser gyros.
