Guidance, Navigation, and Control Laboratory

Department of Aerospace Engineering l Autonomous Unmanned Vehicle Research Center

Sejong University

GNC (Guidance, Navigation, and Control) Lab. since March 2000

We are creating autonomous flying robots that have high-performance, high-safety, and high-reliability for various industrial applications. Our ultimate goal is to develop stable and robust control techniques capable of withstanding harsh environmental conditions and effectively mitigating faults or security attacks. The flying robots are multicopter drones with onboard sensors and processors customized for state estimation, control and planning. We rely on a range of sensors including an IMU, cameras, a laser range scanner, an altimeter, and a GPS sensor. Our smallest drone has a mass of 25 grams with very high agility. Our largest drone is nearly 25kgs and can navigate in harsh environments.
