摘要： In one embodiment, a navigation system may include at least one self-describing fiducial with a communication element to communicate navigation state estimation aiding information comprising a geographic position of the self-describing fiducial with respect to one or more coordinate systems and a first navigating object to receive navigation information from an exterior system, receive navigation state estimation aiding information from the self-describing fiducial, and compare the navigation information received from the exterior system to the navigation state estimation aiding information to improve navigation parameters of the first navigating object.

摘要： In one embodiment, a self-describing fiducial includes a communication element that optically communicates navigation-aiding information. The navigation-aiding information may include a position of the self-describing fiducial with respect to one or more coordinate systems and the communication element communicates the navigation-aiding information to one or more navigating objects in the vicinity of the self-describing fiducial. In another embodiment, the communication element is further configured to communicate supplementary information describing a spatial relationship between the self-describing fiducial and the surrounding environment.
