1. A method of inspecting a navigation safety facility using a flight vehicle, performed by an apparatus including a controller, an interface, an estimator, and a processor, the method comprising:
defining, by the controller, a three-dimensional (3D) flight path for the flight vehicle such that it passes through the navigation safety facility;
receiving, by the interface, a navigation signal value of the navigation safety facility measured by the flight vehicle automatically flying along the defined 3D flight path, and global positioning system (GPS) data of the flight vehicle;
estimating, by the estimator, a distance and an angle of the flight vehicle viewed from the navigation safety facility by analyzing the navigation signal value; and
inspecting, by the processor, the navigation safety facility based on whether coordinates of the flight vehicle identified by the GPS data are included in an area formed by the distance and the angle,
wherein the receiving comprises:
verifying, by the interface, a type of the navigation safety facility which is a target to be inspected; and
selectively receiving, by the interface, a navigation signal value set based on the verified type of the navigation safety facility among navigation signal values measured by the flight vehicle.
