Claim 13:
14. A navigation system for an aircraft, the navigation system comprising:
a first camera configured to capture a first image of a portion of an environment that surrounds the aircraft at a first time and a second camera configured to simultaneously capture a second image of the portion of the environment at the first time, the first camera at a first mounting location and the second camera at a second mounting location offset from the first mounting location; and
a processing component coupled to the first camera and the second camera, the processing component configured to:
receive the first image and the second image;
identify an object of a known location that appears in both the first image and the second image;
determine, for each camera, a distance from the camera to the object and an angle of the camera relative to the object; and
determine a location of the aircraft based on the distances and angles;

wherein the first camera is further configured to capture a third image of a portion of the environment that surrounds the aircraft at a second time and the second camera is configured to simultaneously capture a fourth image of the portion of the environment at the second time, and
wherein the processing component is further configured to:
identify the object in the third image and the fourth image;
determine, for each camera, an updated distance from the camera to the object and an updated angle of the camera relative to the object; and
determine a change in the location of the aircraft to the object based on the updated distances and the updated angles.
