I concur.
Generating the requisite signal is easy to do with opensource code and just $200 or so of equipment.
I bet the drone didn't use the military encrypted GPS because they didn't want encryption keys to fall into the wrong hands (they're global), or just because the effort to load the new GPS keys every week was too much, The attackers just jammed and then spoofed GPS, and by providing a very strong signal, any kalman filters designed to merge signals from inertial units would be fooled.
