DEVICE AND METHOD FOR REFINING AIRCRAFT TRAJECTORY Russian patent published in 2023 - IPC G01C21/00 G05D1/00 G05B13/04 

FIELD: aircraft (AC).

SUBSTANCE: device and a method for refining trajectory of an aircraft (AC). Device contains a display module, a reference trajectory generation module, a trajectory planning module. To refine the movement trajectory, a map of environmental objects is constructed based on a three-dimensional (3D) point cloud obtained from the 3D point cloud generation module contained in the AC, the distance from the AC to the surrounding objects is estimated in a certain way, a reference trajectory for the AC is generated by interpolating the trajectory constructed according to the flight task between the control points in a certain way, a refined trajectory is formed taking into account obstacle avoidance based on the reference trajectory, a map of environmental objects and data on the distance from the AC to surrounding objects, control signals are generated based on the refined trajectory.

EFFECT: increased accuracy of following the initial trajectory of the aircraft in presence of obstacles, improved smoothness of movement and increased flight safety.
