One way is to cary an inertial navigation system and compare you position using INS and GPS and if they differ try and guess which is correct. You can also have the third nab system that uses radar to match the topography. Cruise missile cary all three but then those were designed to cary atomic warheads. My bet is this drone was considered expendable and build as cheaply as something like this can be built I doubt one could spoof GPS to the degree required to land an airplane. But looks at how straight the skin is, I doubt it crashed into the ground either. I suspect this drone did not use any truly sensitive technology as they had to figure a few would crash or get shot down.
