AP UAV methodology.

Someone asked somewhere else what would be neded to get a model to fly a preplanned course at a given altitude, stabilize and take an aerial survey set of pictures.

I decided that some sort of two axis gyro and a GPS system,plus some microcontroller smarts was what would be needed.

What is available to do the GPS? a module or chipset that you can read from a PIC or similar and determine position and altitude?

And how do you determine heading? Or is it a question of simply working it out from repeated position measurements..I know that standard GPS is only accurate to a few meters, but does it have enough resolution to detect a position CHANGE to less then that?
