I agree it is an area that could do with research. However, we know consumer level GPSs have no protection against spoofing (indeed, you can buy GPS jammers from various websites for defeating fleet tracking systems). You could as well use a replay attack against the pilot's control system (probably on 2.4GHz) using much cheaper hardware. There is still plenty of work to do before these class of research drones become commonplace overhead - in particular, practically every onboard system is a single point of failure.
