Position, Navigation, and Timing (PNT) Geofencing - EX-0002

Malware or implanted procedures execute only when the spacecraft’s state meets geometric and temporal criteria. Triggers can be defined in orbital elements, inertial or Earth-fixed coordinates, relative geometry, lighting conditions, or time references. The code monitors on-board navigation solutions, ephemerides, or propagated TLEs and arms itself when thresholds are met (e.g., “only fire over region X,” “only activate during LEOP,” or “only run within N seconds of a scheduled downlink.”) Geofencing reduces exposure and aids deniability: triggers are rare, aligned with mission cadence, and hard to reproduce on the ground. More elaborate variants require conjunctions of conditions (position + attitude + clock epoch) or incorporate drift so the trigger slowly evolves with the orbit. The result is effect-on-demand: execution occurs precisely where and when the actor intends, while remaining dormant elsewhere.
