Method of determining a fire guidance solution

A method of determining a firing guidance or control solution when a relative movement exists between a weapon adapted to fire a projectile and a target object that is to be hit, including the steps of:

• adjusting the weapon in azimuth angle α and in elevation angle ε;
• by means of a movement differential equation solution method, determining a projectile point of impact and a projectile flight time at prescribed values for the azimuth angle α and the elevation angle ε, and also in view of the ammunition used and taking into consideration external influences, especially weather data;
• varying the azimuth angle α and the elevation angle ε, as input parameters of the movement differential equation solution method, until a firing guidance solution is found, taking into consideration the speed of the weapon and the speed of the target object;
• providing a function J (α, ε) that assumes a particular value J*, especially zero, when the azimuth angle and the elevation angle represent a firing guidance solution;
• and
• selectively iteratively varying the azimuth angle α and the elevation angle ε using mathematical processes, especially the zero-point searching method, such that the particular value J* is found.
