Abstract:
A system and method of operating a payload from a high altitude platform. The method involves docking a high-altitude vehicle (10) to a launch vehicle (20). The launch vehicle carries the high-altitude vehicle (10) to an operating altitude where the high-altitude vehicle (10) is released. The payload onboard is placed into operation at the operating altitude. The high-altitude vehicle is replenished as necessary while the high-altitude vehicle (10) is in flight from a replenishment vehicle (20) allowing the high-altitude vehicle to remain in an on-station status. At the completion of the high altitude vehicle flight, the high-altitude vehicle (10) is retrieved from the operating altitude and returned to the surface.
Abstract:
An unmanned rotor carried aerial vehicle comprises a propulsion unit (5) and a carrier (7) suspended from the propulsion unit. The propulsion unit (5) is connected to the carrier (7) via a cardan-like joint (9) for permitting limited tilting of the propulsion unit relative to the carrier in two orthogonal directions corresponding to the roll and pitch directions of the vehicle and for preventing relative movement between the propulsion unit and the carrier in the yaw direction of the vehicle.
Abstract:
A flock of drones provide a drone-assisted mesh network for first responders. Network modules attached to the drones interconnect with other network modules and provide network access points for first responder devices, allowing the first responder devices to communicate with each other via the drone-assisted mesh network. The drones may autonomously reposition themselves to create a desired network coverages area, including adjusting the network coverage area as instructed via a drone controller. The network modules may communicate with a gateway to an external network, allowing first responder devices to communicate with the external network via the drone-assisted mesh network. Network modules may be selected for field-attachment to the drones based on characteristics of the first responder devices.
Abstract:
A system provides one or more support operations for a land vehicle using an unmanned autonomous vehicle (UAV) such as an aerial drone. The support operations are provided via operation of a UAV accessory or accessory module while the UAV is deployed away from the land vehicle. The UAV accessory can obtain information pertaining to the terrain at a terrain mapping zone, and this information can assist in guiding the land vehicle along a selected path to safely traverse the terrain. Wade depth mapping of a water feature is an example of terrain mapping that can be performed by the system. Other types of support operations include emergency support operations, extending the effective reach of wireless signals to and from the land vehicle, and capturing recreational images of the land vehicle.
Abstract:
A drone control method includes commanding a drone launched from a vehicle to execute a predefined schedule of flight commands such that the drone occupies a series of locations within a predefined radius from a buoy, which is also launched from the vehicle, to identify a drone position relative to the buoy associated with a maximum signal strength of the communication signal. The execution of the predefined schedule may be in response to receipt of a communication signal from an emergency responder.
Abstract:
An Unmanned Aerial Vehicle (UAV) comprises a situational awareness system coupled to at least one onboard sensor that senses the location of other UAVs. A cooperative Radio Access Network (RAN)-signal processor is configured to process RAN signals in a UAV-User Equipment (UE) channel cooperatively with at least one other UAV to provide for increased rank of the UAV-UE channel and produce RAN performance criteria. A flight controller employs autonomous navigation control of the UAVs flight based on the relative spatial locations of other UAVs and the RAN performance criteria operating within predetermined boundaries of navigation criteria. The UAV can be configured to employ mitigation tactics against one or more UEs identified as a threat and may coordinate other UAVs to conduct such mitigations.
Abstract:
According to some embodiments, an unmanned vehicle includes a power supply configured to supply an electrical power signal to a motor for propelling the unmanned vehicle, a wireless communication device configured to transmit or receive a radio frequency (RF) signal, and a motor feed antenna coupled to the power supply and the wireless communication device, the motor feed antenna configured to conduct the electrical power signal from the power supply to the motor, and to transmit or receive RF signals as an antenna for the wireless communication device.
Abstract:
Systems and methods for detecting an unmanned aerial vehicle (UAV). Network access (for example, to the Internet) may be provided by detecting a UAV and fixing one or more beams from one or more ground terminals to the UAV. In one embodiment, the detection of a UAV includes forming and pointing beams from a ground terminal and ground gateways toward the UAV. The ground terminal may be configured to autonomously steer its antenna beam during initial installation to detect the reference signal from a UAV. In one variant, the ground terminals are steered to more finely track the position of the UAV based on a signal quality metric such as received signal strength. In one embodiment, the ground terminal antenna is initially manually pointed toward the UAV, and thereafter allowed to automatically steer to track the position of the UAV.
Abstract:
Systems and methods configured to form and point beams from one or more unmanned aerial vehicles (UAVs) toward a target coverage area on the ground. One embodiment describes dividing the target coverage area on the ground among multiple UAVs when each UAV antenna system generates static beams. Another embodiment describes dividing the target coverage area on the ground among multiple UAVs when their antenna systems are capable of dynamically steering their respective beams. Another set of embodiments describe systems and method to allow multiple UAVs to provide service in the same area on the ground using the same spectrum.
Abstract:
A method of communication link accessibility aware navigation is provided that includes querying a communication link accessibility map based on a location of interest provided by a path planner for a communication node. A communication link accessibility indicator is received representing a communication link characteristic associated with the location of interest in response to querying the communication link accessibility map. A communication link accessibility weight is determined based on a mission priority of maintaining a communication link of the communication node. The communication link accessibility weight is applied to the communication link accessibility indicator.
