Well, you didn't mention that.

You may consider using a 3D compass to keep the gyros straightened out, if the compass drift is better than the gyro drift. No matter what you do you can't get better than the worst sensor. If you could set out beacons of some sort for the thing you may be able to use them to enhance accuracy, but then you'll be restricted to only working where the beacons are set up, and you'll have to invent the beacon system.
