## What it is
GAAS (Generalized Autonomy Aviation System) is an open-source C++ framework for fully autonomous VTOL aircraft and drones, built around lidar-based localization, HD-map relocalization, and path planning. It provides a loosely coupled modular autonomy stack intended for human-carrying flying cars and large cargo drones, integrating automotive-grade self-driving technologies.

## Use cases
- autonomous drone flight stack
- lidar-based localization for UAVs
- path planning for flying vehicles
- HD-map relocalization in the air
- flying car autonomy research
- cargo drone navigation
- obstacle avoidance and replanning for aircraft

## When to choose
- building autonomous VTOL or large drone systems
- researching lidar-based aerial localization and planning
- needing a modular autonomy framework you can extend with custom modules
- integrating air-traffic-control-compatible autonomy

## When to avoid
- consumer camera-drone autopilot features
- vision-only SLAM projects
- projects needing active community maintenance or frequent releases
- non-ROS or non-Linux environments

## Facets
- artifact type: framework
- maturity: maintenance
- function: simulation, machine-learning, computer-vision, robotics, middleware
- domain: autonomous-vehicles, robotics, simulation
- platform: cpp
- tags: drone, vtol, flying-car, lidar, hd-map, path-planning, uav, autonomous-flight, px4, gazebo, drones, linux, ros
