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 vehicle and deployable location marking system for deploying from a vehicle includes a vehicle including an exterior frame and an undercarriage. A power source is mounted on the vehicle and an electromagnet is coupled to the undercarriage of the vehicle and is electrically coupled to the power source. A switch is electrically coupled to the electromagnet and is mounted on the steering wheel, wherein the switch turns on or off a magnetized condition the electromagnet. A beacon for marking a location is releasably coupled to the electromagnet and releases from the electromagnet when actuated by the switch to a demagnetized condition.

Localization systems and methods for transmitting timestampable localization signals from anchors according to one or more transmission schedules. The transmission schedules may be generated and updated to achieve desired positioning performance. For example, one or more anchors may transmit localization signals at a different rate than other anchors, the anchor transmission order can be changed, and the signals can partially overlap. In addition, different transmission parameters may be used to transmit two localization signals at the same time without interference. A self-localizing apparatus is able to receive the localization signals and determine its position. The self-localizing apparatus may have a configurable receiver that can select to receive one of multiple available localization signals. The self-localizing apparatuses may have a pair of receivers able to receive two localization signals at the same time. A bridge anchor may be provided to enable a self-localizing apparatus to seamlessly transition between two localization systems.

A method for managing the transmission of geographical locations from a geolocation beacon during the movement thereof. The method includes: defining a first reference communication network associated with a first value and with a reference frequency used for the transmission of the locations over the first network; locating the beacon in a second network during the movement thereof; obtaining a second value associated with the second network; comparing the first and the second value, and when the values differ, the method includes modifying the reference frequency for the transmission of the locations over the second network.

A method is disclosed comprising: scanning for one or more signals sent by one or more beacon devices, wherein each signal of the one or more signals comprises an identifier of the beacon device, which has sent the signal of the one or more signals, wherein one or more identifiers of the one or more beacon devices are determined based on the one or more signals of the one or more beacon devices; obtaining a position information representing the position of the at least one first apparatus; and outputting a report information comprising the determined one or more identifiers of the one or more beacon devices and the position information of the at least one first apparatus to allow usage of the outputted report information to determine the position of at least one of the one or more beacon devices. A corresponding apparatus, computer program and system are also provided.

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.

The present inventive concept includes a duct system and method for using same to map and locate ducts. A preferred embodiment of the duct system includes a duct, a plurality of electronic information modules and an oversheath at least partially covering the plurality of information modules and fixing the information modules to the duct. The plurality of information modules are configured to emit a positional signal to enable location of the information modules and associated duct(s) and/or mapping of the duct system.

A user enters a location with a user device. A beacon device broadcasts a first beacon device code comprising a hardware identifier via a local wireless network at the location. A service application of the user device receives the first beacon device hardware identifier, logs a check-in status of the user, and transmits the check-in status to a service provider system. The beacon device generates, after a predetermined period of time, a subsequent beacon device code comprising a random number to broadcast at the location via the local wireless network. In response to receiving the subsequent beacon device code broadcast by the beacon device, the user device logs and transmits a subsequent check in status to the service provider system via the network. The service provider system provides services to the user device or another device at the location in accordance with the check-in status of the user device.
