*Ideally* I would like to build an sudo-autopilot for a RC plane. I basically want to create a program so I can use my laptop (hooked up to the radio) as my controller. My goal would be to get it to the point where i can type "take-off" and the plane would take off, or "land" and the plane would land. Obviously there will be MANY restrictions to where and when this would work on an RC plane since clearly I would have no radar or advanced control systems on the plane. For instance the place I'm flying would have to be completely flat land since it will not be able to detect where the ground is, and I'm not looking for it to be able to handle a ton of wind.
So what I'm wondering is if there are any suggestions on what to use for positioning. GPS I know is a definite possiblilty but isn't it only accurate to with in 20 feet or so. And how well does it show height change since that is the direction I need it to be most accurate in, I figure I can *zero* ground level before it takes off. Any comments on this or any suggestions on other means for positioning data? Thanks
