An automatic landing system includes an imaging device mounted on a vertical take-off and landing aircraft; a relative-position acquisition unit that performs image processing on an image of a marker at a target landing point, and that acquires a relative position between the aircraft and the target landing point; a relative-altitude acquisition unit for acquiring a relative altitude between the aircraft and the target landing point; and a control unit for controlling the aircraft in a plurality of control modes so that the relative position becomes zero. The control modes include a hovering mode in which the relative altitude of the aircraft is lowered to a predetermined relative altitude when the relative position is within a first threshold value. A transition to a landing mode occurs upon satisfying predetermined conditions including the relative position being within a predetermined threshold value less than the first threshold value.

The invention relates to a guidance system for leading an aircraft to a reference point, characterised in that it comprises: An active beacon capable of emitting a first electromagnetic signal in a first emission cone, defined by an apex coinciding with the reference point, a first beam angle and a first axis corresponding to an emission direction; and a multi-beam radar, installed on board the aircraft, operating in reception mode and capable of performing deviation measurements on a signal received from the active beacon, the multi-beam radar comprising an antenna adapted for receiving in at least two spatially separate reception cones.

Systems, apparatus, and methods for remote monitoring and piloting of a ship. Examples include a method of delivering remote monitoring equipment to the ship and establishing a data and communication exchange for shore-based pilotage of the ship from a remote location. The equipment usable for remote monitoring and communication between the ship and pilot (at the remote location) is stored in a package and delivered to the ship by unmanned aircraft. The package is distributed and installed by ship's crew to specified locations. The remote pilot while located ashore has access to all the information that is needed to assist in safe navigation of the ship by exchanging data and/or streaming real time video from the ship to shore. Additionally, the system may extract navigational data from the ship and transmit it to shore in real-time.

An aircraft position control system includes a feedback control unit configured to calculate a feedback manipulated variable of an aircraft by feedback control so that the aircraft heads toward a target landing point, based on at least the relative position and the relative velocity; a multi-value control unit configured to set, by referring to a switching line preliminarily provided in a manner passing through an origin of a coordinate plane whose orthogonal axes represent the relative position and the relative velocity and separating an acceleration region in which the relative velocity is to be increased and a deceleration region in which the relative velocity is to be decreased, an addition value that tends to increase the relative velocity when a coordinate point of the current relative position and the current relative velocity is located in the acceleration region to calculate a manipulated variable of the aircraft

The present disclosure provides a method for controlling a drone, a drone, and a system. The method for controlling a drone comprises: determining operating parameters of a moving platform according to field-of-view images containing the moving platform collected at any two different moments and flight parameters of the drone; calculating a time-varying tracking position of the moving platform based on the operating parameters; controlling the drone to track the moving platform according to the time-varying tracking position of the moving platform; and controlling the drone to perform a landing operation according to a relative position of the moving platform and the drone during tracking. The technical solutions according to the present disclosure have high landing accuracy, rely less on device performance and have high versatility.

Example UAV landing systems and methods are described. In one implementation, a landing platform includes a conveyor belt capable of supporting an unmanned aerial vehicle (UAV). The conveyor belt can move in a first direction and a second direction that is opposite the first direction. The landing platform also includes a first positioning bumper and a second positioning bumper, where the first positioning bumper and the second positioning bumper are capable of repositioning the UAV on the conveyor belt. The landing platform further includes a cradle that can receive and secure the UAV.

A landing system suitable for receiving an unmanned aerial vehicle (UAV) comprises an autonomous ground vehicle (AGV). A landing surface is disposed on the AGV, and the landing system comprises a loading channel suitable for passing an object delivered by the UAV through a first loading channel opening in the landing surface. The object passes within the loading channel through to a second loading channel opening at a bottom aspect of the AGV. In this way, a UAV can land on the landing surface, and the AGV positions the object in line with a target delivery location, where the object is delivered. Aspects of the landing system comprise an electromagnet or vacuum chamber for securing the UAV to the landing surface, thereby enhancing stability of the UAV during movement of the landing system.

The embodiments are an aircraft return control method and device, an aircraft and a storage medium. The method includes: determining the location of a return target region according to the time and the phase of a return signal; and when flying to the return target region, according to a matching result between an image of a current region and a pre-collected image of the return target region, adjusting flight parameters to land at the return target. Embodiments of the present invention solve the technical problem in the prior art that the aircraft cannot be accurately landed at the return target due to the movement of the return target, and achieve the technical effect of controlling the aircraft to accurately and safely land at the return target on the return target region.

In aspects herein, if GPS signals used as inputs into a GPS landing system become unreliable, an aircraft instead uses signals derived from radar data to operate the GPS landing system. Generally, GPS signals are unreliable if they cannot be received or if the signals are corrupted. Instead of using GPS signals, the landing system uses radar derived location data as inputs. In one example, the radar derived location data is generated using a radar system located at the intended landing site—e.g., an airport or aircraft carrier. The landing site transmits this data to the aircraft which processes the data using its GPS landing system that outputs control signals for landing the aircraft. Thus, even when GPS signals are unreliable, the aircraft can use the GPS landing system to land.

Devices such as vehicles, remote sensors, and so forth consume energy during operation. Described herein are systems, devices, and methods for transferring energy from an uncrewed autonomous vehicle to a vehicle such as a car. The uncrewed autonomous vehicle may locate the vehicle at a rendezvous location, and connect with the vehicle while the vehicle moves. Once the uncrewed autonomous vehicle connects to the vehicle, the uncrewed autonomous vehicle may transfer the energy to the vehicle.
