METHOD FOR TRAJECTORY CONTROL OF A GROUP OF UNMANNED AERIAL VEHICLES WHEN MONITORING URBAN DEVELOPMENT Russian patent published in 2022 - IPC G01R31/00 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to methods for trajectory control of a group of unmanned aerial vehicles (UAVs) and can be used to ensure the flight safety of a group of UAVs when solving monitoring tasks. The proposed control method will improve the flight safety of a group of UAVs by using automation of the obstacle avoidance process in a predetermined area of the city in a horizontal plane with a low-altitude flight of a group of UAVs. The object of urban development is approximated by a rectangle. Correction of the course angle of the i-th UAV begins when there is a deviation of the constructed flight path for the i-th UAV from the initial specified rectilinear trajectory, and stops when the i-th UAV covers the entire trajectory and reaches the intended i-th flight point. At the same time, the use of this invention makes it possible to increase the efficiency of operators by unifying the description of a typical urban development area in the proposed way.

EFFECT: use of the invention will make it possible to ensure a safe flight by a group of UAVs over urban areas in the horizontal plane by correcting the flight path of each unmanned aerial vehicle moving along a pre-planned route.
