3D Solid State Gyro

Thanks, I did know why I didn't think of Google, I use for everything else.;-)

Can you point me to a tutorial on "3D Solid State gyroscope".

Short FOG info is at:

MEMS units:
http://www.omniinstruments.co.uk/gyro/gyro.html

Both are solid state units. FOG units will give lower drift, but are higher
in price than the MEMS units. There are also other basic designs and most
are tradeoffs between cost, environmental specs and performance. Google
will give you many more hits.

You caught me. I was looking at an advertisement for a handheld and it peeked my
curiosity about solid state gyro's.

GeorgeC,

You could have put it a little kinder, but thanks.


Sorry, it was late here ;-) Hope you found something - I did when I
tried.

In that case, you're interested in the MEMS type also used by the G1000 and
Avidyne's Entegra.

Don't some of those "gyros" actually use microelectronic-sized metal
beam with a "weight" on the end. Deflection is proportional to
acceleration. Integrate acceleration to get velocity. Again to get
position. You can do the same thing with rotation. I've always
wondered how accurate those little things are and how they react to heat.

IIRC Stanford University was experimenting with them on a DARPA contract
years back. They wanted to build a wing-leveler by using two such
devices, one on each wing tip.

I did Goggle "Solid State Gyroscope", per your suggestion. All I got were
product description and application suggestion. Next, I'm going to Goggle on
some of the leads I got from the first search.

Also, try piezo electric gyro. They are much lower Tec, drift quite a lot,
and need something to adjust for drift, frequently.

Your question got me interested in the subject, so I did a search on the
U.S. Patent & Trademark website for "Fiber Optic Gyroscope" which resulted
in this, among other hits:

http://www.uspto.gov/web/patents/pat...-20060124.html

I still don't quite understand the "no moving parts" claim from the
manufacturers.

So what is moving? Light? That does not qualify as a part, IMHO.
