Hi all! Back in Fl from my trip to the great white north. A bit of trivia. It'll be 30 here overnight. BRRRRR.
An idea that Phil proposed, I've researched and found a possible part. The 9dof imu idea really makes sense. Most of these are stand alone Arduinos in and of themselves. Good example from the near east on the fave rave auction site: 271015460402
The fact that it passes the data over a serial port makes it attractive, as the setup for the device can be done by novices. Note that the data wouldn't be sufficent to pilot an aircraft, but should be perfectly adequate for heading and attitude information to point an antenna.
Having a built in compass makes setup in the field a snap. Just think. Plop the tripod down, turn it on and it will tell where you're pointed. No more gps/compass for finding beam headings.
