rgallant:
It does all seem to be flight based that's for sure. But can you define your parameters a bit better, when you say navigate via gps do you mean move from known starting point to a known waypoint ? Or from a known start point to a waypoint that is identified by a system other than gps coordinates ?
Sorry--didn't see your post!
what do you mean flight based? And navigating for starters will consist of the Arduino knowing its current position and the coordinates of the goal it want to get to. Later programming might involve other waypoints, but right now I'm sticking with going from point "a" (current position) to "b" (another, known position--but not the current position)
Also a next revision is probably going to include GPS differential, but that's a bit out of my reach currently
