Modern Missile Guidance Problems

Both, in general, most missiles are guided in the direction of predicting the position of the hit target, i.e. inertial guidance. And now there is the emergence of Excalibur GPS-guided artillery shells as a representative of the current position of the target as the direction of guidance to hit the target.

(In my opinion, in terms of the capability of the Excalibur GPS-guided artillery shell, it is a missile.)
