Abstract: An error correcting location system includes a ground station with fixed reference coordinates. The ground station may receive satellite broadcast messages from a plurality of location system satellites. Further, the ground station may determine location coordinates based on the satellite broadcast messages, and compare the location coordinates to the fixed reference coordinates to determine a compensation value. In addition, the ground station may send the compensation value to location system devices. Upon receipt of the compensation value, the location system devices may utilize the compensation value to generate highly accurate location coordinates.

Abstract: This disclosure describes a configuration of an unmanned aerial vehicle (UAV) landing gear assembly that includes adjustable landing gear extension that may be extended or contracted so that the body of the UAV is contained in a horizontal plane when the UAV is landed, even on sloping surfaces. For example, when a UAV is landing, the slope of the surface may be determined and the landing gear extensions adjusted based on the slope so that the body of the UAV remains approximately horizontal when the UAV lands and is supported by the landing gear extensions.

Abstract: A configurable unmanned aerial vehicle (UAV) may include swappable avionics that may be selectable for use with other UAV components to build a customized UAV just prior to deployment of the UAV that is configured to deliver a package to a destination. Various factors may be involved in the selection of the avionics, such as an availability of different avionics, payload requirements (size, weight, etc.), environmental conditions along an anticipated route of flight, a region of use of the UAV, compatibility, a distance of the flight, power considerations, security considerations, and/or other factors. The avionics may include various hardware and/or software which may provide control output (e.g., data, power, and/or mechanical) to other components and/or systems, including a propulsion system. Coupling devices may selectively couple the avionics to other components of the UAV, such as to a battery, a cargo bay or package, and/or to a propulsion system.

Abstract: Beacon pods that provide location information to unmanned aerial vehicles (UAVs). The beacon pods may emit location information, which may replicate global positioning system (GPS) satellite information, provide a homing signal, provide access to a mobile telephone network as a signal repeater or booster, and/or provide other information and/or connectivity to a UAV, which may aid navigation and/or other operations of UAVs. The beacon pods may be configured for use in a residential location, which may enable a beacon pod to connect to residential power and computing networks. The beacon pods may establish secure data communication with UAVs and may log events related to UAVs, which may be used for various purposes.

Abstract: A temperature-controlled payload container that may be used by an unmanned aerial vehicle (UAV) to transport perishable items and/or items desired to be at or near a specific temperature upon arrival at a destination. The temperature-controlled payload container may be used to maintain or adjust a temperature of a delivery item, such as a food item. In some embodiments, the temperature-controlled payload container may be capable of heating items in a first portion of the container and cooling items in a second portion of the container. For example, the container may be divided by a Peltier junction, which is an electrified junction of two different conductors. In some embodiments, the temperature-controlled payload container may receive heat generated from operation of the UAV.

Abstract: Systems and methods for providing a series of multiuse UAV docking stations are disclosed. The docking stations can be networked with a central control and a plurality of UAVs. The docking stations can include a number of services to facilitate both UAV guidance and maintenance and community acceptance and benefits. The docking stations can include package handling facilities and can act as a final destination or as a delivery hub. The docking stations can extend the range of UAVs by providing recharging/refueling stations for the UAVs. The docking stations can also include navigational aid to guide the UAVs to the docking stations and to provide routing information from the central control. The docking stations can be incorporated into existing structures such as cell towers, light and power poles, and buildings. The docking stations can also comprise standalone structures to provide additional services to underserved areas.

Abstract: A prognostic failure detection system may be implemented for an unmanned aerial vehicle(s) (UAV). A prognostic failure detection system may include a process of predicting failure conditions that may affect an UAV physical system or structure before they occur. By predicting failure conditions before they occur, the prognostic system allows maintenance centers to perform corrective actions in a timely and cost-effective manner. The prognostic system is intended to monitor and support the functionality of several physical systems and physical structures associated with an UAV. A physical system includes, but is not limited to, the electrical system, power system including the power supply, motor and propeller assemblies including motor controllers, navigation system, and flight controller system.

Abstract: This disclosure is directed to an automated unmanned aerial vehicle (“UAV”) self-identification system, devices, and techniques pertaining to the automated identification of individual UAVs operating within an airspace via a mesh communication network, individual UAVs and a central authority representing nodes of the mesh network. The system may detect nearby UAVs present within a UAV's airspace. Nearby UAVs may self-identify or be identified via correlation with one or more features detected by the UAV. The UAV may validate identifying information using a dynamic validation policy. Data collected by the UAV may be stored in a local mesh database and distributed to individual nodes of the mesh network and merged into a common central mesh database for distribution to individual nodes of the mesh network. UAVs on the mesh network utilize local and central mesh database information for self-identification and to maintain a dynamic flight plan.

Abstract: An unmanned aerial vehicle (“UAV”) is configured with a redundant power generation system on-board the UAV. A redundant power system on-board the UAV can selectively utilize an auxiliary power source during operation and/or flight of the UAV. The power system on-board the UAV may include a battery and at least one auxiliary power source comprising a combustion engine. The combustion engine on-board the UAV may be selectively operated to charge the battery when a charge level of the battery is below a full charge level, and/or to power one or more propeller motors of the UAV.

Abstract: An unmanned aerial vehicle (UAV) may be used for delivering products or other articles. The UAV is configured to detect the presence of nearby people, animals, or other interactive objects. Upon detecting a nearby object, the UAV may produce speech in order to warn or instruct the object. The UAV may also have speech input capabilities in order to capture and respond to speech from the object. The UAV may conduct a speech dialog with a nearby person in order to request information and/or answer questions from the object. In certain situations, the UAV may detect whether an object is in the way of a desired landing area and may communicate with the object through speech to ask the object to move or to ask the object to specify an alternative landing area.
