This project proposes a software solution that enables a swarm of cooperating aerial vehicles to perform surveillance of unknown hostile environments during GPS denial. Cooperative exploration of adversarial environments poses significant challenges: (i) the vehiclesÂ’ motion can be tracked, leading to the vehicle being destroyed or captured, (ii) GPS can be jammed or spoofed, or (iii) communications can be detected. The proposed solution will address these challenges by: (i) minimizing successful attacks by generating unpredictable trajectories that are tuned to possible attacks in the area, (ii) enabling relative localization in GPS denial, and (iii) minimizing communication events.
