GAAS

GAAS, or Generalized Autonomy Aviation System, is an open-source autonomy framework for drones, VTOL aircraft, and experimental flying-car research. It focuses on robust autonomous navigation using lidar rather than relying primarily on vision. The system includes mapping, HD-map localization, path planning, obstacle handling, and aircraft-control modules. Localization components include NDT and ICP approaches, with GPU acceleration available for selected algorithms. Simulation support integrates lidar, stereo cameras, PX4, Gazebo, and AirSim environments. Its modular C++ architecture allows individual autonomy components to be replaced or extended. The repository targets research rather than production aviation and reflects an older robotics stack centered on Ubuntu 18.04 and ROS Melodic.
