Method and system for controlling the automatic landing/take-off of a drone on or from a circular landing grid of a platform, in particular a naval platform

A method for controlling the automatic decking/take-off of a drone (4) on or from a circular decking grid (5) of a naval platform (1), characterized in that it comprises the following steps:

• a step for acquiring the movements of the grid (5),
• a step for calculating the mean position of the grid (5),
• a step for calculating grid position predictions (5),
• a step for calculating minimum displacement speeds of the grid (5), and
• a step for acquiring the position of the drone (4) in order:
• if the drone (4) cannot follow the movements of the grid (5) and if the movements of the grid (5) are small, that is to say less than the radius of said grid, to apply a landing strategy by following the mean position of the grid, whereas, if the movements of the grid are large, that is to say greater than the radius of the grid, to apply a landing strategy by positioning at the minimum speeds of the grid;
• and
• if the drone (4) can follow the movements of the grid and if the movements of the grid (5) are small, that is to say less than the radius of the grid, to apply a landing strategy according to the mean position of the grid, and if the movements of the grid are large, that is to say greater than the radius of the grid, to apply a landing strategy by following the grid position predicted at the moment of decking.
