Systems and methods for navigating an aerial vehicle are provided. One example aspect of the present disclosure is directed to a method for navigating an aircraft. The method includes receiving, by one or more processors, one or more first geographic coordinates via an interface configured to receive geographic coordinates from a satellite transmission. The method includes receiving, by the one or more processors, one or more second geographic coordinates via an interface configured to receive geographic coordinates from a ground transmission. The method includes determining, by the one or more processors, that the one or more first geographic coordinates and the one or more second geographic coordinates are inconsistent. The method includes updating, by the one or more processors, a flight plan using the one or more second geographic coordinates when the one or more first geographic coordinates are inconsistent with the one or more second geographic coordinates.

A marker for burying adjacent an underground structure such that a location of the underground structure can be identified from above a ground surface. The marker comprises a housing, a self-orienting beacon retention device disposed within the housing. The self-orienting beacon retention device comprises a coil bobbin, and an inductance-capacitance beacon device carried by the self-orienting beacon retention device. A coil of the LC beacon device is disposed around an exterior surface of the coil bobbin. The self-orienting beacon retention device is structured and operable to orient the coil bobbin and the inductor coil in a desired orientation relative to a ground surface regardless of the orientation of the housing relative to the ground surface.

A marker for burying adjacent an underground structure such that a location of the underground structure can be identified from above a ground surface. The marker comprises a housing, a gimbal beacon retention device pivotally disposed within the housing, and a beacon device carried by the gimbal beacon retention device. The gimbal beacon retention device is structured and operable to orient the beacon device in a desired orientation relative to a ground surface regardless of the orientation of the housing relative to the ground surface.

A method for virtual navigation and communication radios in a vehicle is provided. The method includes receiving a request for a selected radio function, determining a position of a vehicle, determining the data to provide for the selected radio function based on the vehicle position, receiving or generating the data for the selected radio function, and providing the received or generated data over an interface associated with the navigation or communication radio.

The disclosed embodiments include computer-implemented devices, systems, and methods that determine a position of a terminal device within a communications environment. In one embodiment, a positioning device may include a memory and one or more processors. The one or more processors may be configured to change a variable to be transmitted to a user device, to store the changed variable in the memory, and to output a first signal indicating that the user device is present in a predetermined area, based on a first variable received from the user device and the changed variable stored in the memory.

A system and method for identifying a customer's location at a business and provide notification to a company representative upon arrival of the customer at the business location. Real-time location determinations for the customer and customer location tracking can be provided. One or more wireless beacons communicate with the customer's electronic device. The beacons provide the system with real-time data about the customer's whereabouts, allowing for the confirmation and tracking of the customer at the location. A first non-limiting example of use, include a company that provides food and beverage allowing the customer to place an order for food and beverages on their electronic device and having the order delivered to the person at their current location as determined by the system. Another non-limiting example includes a company using the notification system to have assigned staff members notified of the customer's arrival.
