Editing Missile guidance (section)

==Categories of guidance systems==

Guidance systems are divided into different categories according to whether they are designed to attack fixed or moving targets. The weapons can be divided into two broad categories: ''Go-onto-target'' (GOT) and ''go-onto-location-in-space'' (GOLIS) guidance systems.<ref name=zarc /> A GOT missile can target either a moving or fixed target, whereas a GOLIS weapon is limited to a stationary or near-stationary target. The trajectory that a missile takes while attacking a moving target is dependent upon the movement of the target. A moving target can be an immediate threat to the missile launcher. The target must be promptly eliminated in order to preserve the launcher. In GOLIS systems, the problem is simpler because the target is not moving.
