Method for acquiring the coordinates of a triggering point of a projectile and fire control implementing such a method

A method for acquiring the coordinates of a trigger point of a projectile or of a burst of projectiles on trajectory and above a plot of land on which a target is located, the method comprising the following steps:

• performing a three-dimensional acquisition of the plot of land using a means for laser observation,
• constructing by calculation from this acquisition, and then displaying on a means for visualization for an operator, an image of the plot of land from a bird's eye view observation direction, that is, an observation direction from a point located at the vertical and higher than the means for observation,
• positioning, in a manner changeable by the operator, on the thus-calculated image an area of effectiveness which is an image of a geometrical surface or volume allowing to visualize the area or volume of effectiveness of the projectile or of the burst considered when triggered at a trigger point,
• recovering the coordinates of the trigger point desired for the projectile or the burst when the operator has selected the location that suits him after having moved said area on the image of the land.
