Why use this?

PX4 is an open-source flight-control stack for drones, underwater vehicles, boats, and other unmanned systems. It provides flight modes, sensor fusion, navigation, mission planning, failsafes, telemetry, and integration with ground-control software and simulation environments.

Engineers choose PX4 when building autonomous vehicles that need a mature, modular autopilot rather than a closed commercial stack. Its hardware-agnostic architecture, large developer ecosystem, and support for both consumer and industrial platforms make it a leading choice for research, prototyping, and production UAV systems.
