Embodiments of the present disclosure provide a method, an apparatus, a terminal, and a storage medium for elevation surrounding flight control. The method includes: obtaining surrounding parameter information of an unmanned aerial vehicle; determining, according to the surrounding parameter information, an elevation surrounding trajectory to be surrounded, where the elevation surrounding trajectory is a plane with the point of interest as a center and the surrounding radius as a radius, and the plane where the elevation surrounding trajectory is located is perpendicular to a horizontal plane; controlling the unmanned aerial vehicle to fly along the elevation surrounding trajectory.

The influence of multipath on the positioning calculation based on positioning signals transmitted from satellites is reduced. A self-position is estimated using a positioning calculation result based on a positioning signal transmitted from a satellite. Movement of a mobile body is controlled on the basis of the estimated self-position. A multipath reduction action signal is output when the mobile body is in a multipath environment. The mobile body is controlled so as to take a multipath reduction action when the mobile body is in a predetermined movement state and the multipath reduction action signal is output.

A method includes detecting an obstacle in a navigation path of a drone, determining a classification of the obstacle, determining whether to temporarily land based on the classification of the obstacle, and temporarily landing the drone until the obstacle clears the navigation path of the drone.

A method for controlling an unmanned aerial vehicle (UAV) includes determining whether the UAV is within a first flight restriction zone or a second flight restriction zone and effecting a restriction on the UAV in accordance with a result of the determination, including prohibiting the UAV from flying in response to determining that the UAV is within the first flight restriction zone, or controlling the UAV to fly below a flight ceiling in response to determining that the UAV is within the second flight restriction zone.

A control method is provided, including: obtaining a current altitude of an aircraft, and determining a preset horizontal deviation threshold corresponding to the current altitude; obtaining a current horizontal deviation, wherein the current horizontal deviation is a horizontal deviation between a landing position and a current position of the aircraft; and determining a landing strategy of the aircraft based at least in part on a comparison between the current horizontal deviation and the preset horizontal deviation threshold.

A movable object includes one or more processors individually or collectively configured to assess a location of the movable object, calculate a distance between the movable object and a restricted region using the location of the movable object, assess whether the distance falls within a first distance threshold, and instruct the movable object to take a movement response measure selected from (1) a first movement response measure when the distance falls within the first distance threshold, and (2) a second movement response measure different from the first movement response measure when the distance falls outside the first distance threshold. The first movement response measure is related to a current movement status of the movable object.
