The Problem Drones are useless without GPS. GPS jamming in Ukraine took out 85% of some squadrons. Indoors, urban canyons, forests — GPS simply fails. Military solutions cost $50K+. Academic code is unmaintained. There's no real open-source answer for GPS-denied drone flight. What I Built GhostPilot — an open-source visual-inertial SLAM + agentic AI navigation stack that lets any drone fly without GPS. Key Features Visual-Inertial SLAM : Camera + IMU fusion for 6DOF pose estimation — no GPS needed Agentic Mission Planner : Natural language commands → executable navigation goals "Fly to the third floor, check each room for occupants, land at the helipad" "Inspect the roof, avoid personnel, resume path at waypoint B" Nav2 Integration : Industry-standard path planning + obstacle avoidance Edge-Native : Runs on Jetson Orin / Raspberry Pi 5, no cloud dependency Quick Start git clone https://github.com/amsach/GhostPilot.git cd GhostPilot ./scripts/setup_jetson.sh ros2 launch ghostpilot_gazebo…
