Drone Link Defense: Spectrum Waterfall & GPS/INS Track Console

Two of the real defensive layers behind a drone's command-and-control link, rendered as a live 2D instrument console. A scrolling waterfall stacks every hop of the command link's frequency-hopping sequence as one column, channel on the vertical axis — switch from a keyed pseudorandom hop to a sequential, unkeyed one and watch a follower jammer's red band swallow almost the whole track. Below it, a top-down map plots the drone's true position, its independent inertial dead-reckoning estimate, and its reported GPS fix; trigger a spoofing attack and drag around the map to watch the GPS fix peel away from the true track until the onboard cross-check raises the alarm and falls back to INS-only navigation.
