Drone Link Defense: FHSS Anti-Jamming & GPS Spoofing Detection

Two of the real defensive layers behind a drone's command-and-control link, rendered as one live 3D model. A ring of channels around the aircraft shows its command link retuning every hop under a keyed pseudorandom sequence, resisting a jammer that can only guess at a fraction of the spectrum — switch to a sequential, unkeyed pattern and watch a follower jammer lock straight onto it. Above the aircraft, satellites feed a GPS position while the airframe's own inertial dead-reckoning track quietly runs in parallel; trigger a spoofing attack and watch the two diverge until the onboard cross-check raises the alarm and rejects the corrupted fix.
