If you add some sort of tilt sensors, you can use these sensors with a
pretty good accuracy up to a 40 degree tilt. If you create a full 6 degree
sensor solution, I guess you would end up with a complete 3D orientation.
However, you'll need a fair amount of sensors and plenty of math to work it
all through though.

We're using these in a tilted environment. But we don't really go over the
40 degree tilt value.

Regards,
Claudio

If anyone has any luck using these units for 3D orientation I would sure
like to hear about it. I have been playing with the samples I received for a
while now and they seem to be best for getting a bearing direction while in
a horizontal position. As soon as they tilt you need something to measure
the tilt to compensate. The rep that I spoke to said they would not really
work for my application ( a "product" that flies through the air, rotating
with a need for 3D orientation). I am planning to use the 2D version for my
application, but it will keep the sensor in a horizontal position while the
readings are taking place. They are pretty cool sensors and not too
difficult to interface.

They are pretty good about sending free samples as well.
