Systems and methods for inspecting aircraft via an unmanned aerial vehicle (UAV) system are disclosed. In some implementations a system, comprises an unmanned aerial vehicle (UAV) and a computing system configured to establish a coordinate system in a space exterior to the aircraft in a global positioning system (GPS) denied environment. The system also has a controller configured to navigate the UAV along a flight path proximate to a surface of an aircraft according to the established coordinate system and a camera configured to obtain image data. A light detection and ranging (LiDAR) sensor is configured to obtain LiDAR sensor data of an inspection location on the surface to determine a presence of damage.
