Abstract:
A process for a satellite-assisted correction of the path of a trajectory of a ballistically or quasi-ballistically fired projectile, the trajectory path being measured in conformance with an expected offset from a target by an increase in the aerodynamic drag coefficient of the projectile causing said projectile to divert from an initial trajectory segment into a steeper transitional trajectory segment towards the target, wherein external disruptive influences acting on the configuration of the trajectory path are taken into consideration in a predictive determination of an imminent real trajectory beyond the target by, selectively, sensor means and the measured trajectory path in comparison with a computationally derived trajectory, wherein for the expected real trajectory, on the basis of said external disruptive influences, there is determined an initiating point as closely as possible preceding the target for effecting an increase in the aerodynamic drag coefficient causing entry into said steeper transmittal trajectory segment so as to turn the projectile into an accurately targeted minimum trajectory segment.
