Quad encoder problems

[SteveB]

Smitty,
Here is an interesting link to a site on a homebrew UAV. It deals with the problems associated with accurately calculating attitude of an aerospace vehicle. You may get some ideas you can implement on a smaller/limited scale to achieve your objectives.


Better link, check out items under "Design:". Particularly AHRS and Sensors.

HTH,
Steve

EDIT: One final note, there is a reason the off the self systems are very expensive. It is not a trivial task!
