A method for trajectory correction of a projectile, which is terminal phase-guided, after a detection of a deviation of the projectile by a sensor on a weapon, the method comprising:
- triggering a first laser beam over a specific region about a desired course of the projectile, which simultaneously triggers a start of a time counter;
- transmitting an additional rotating laser beam with a fixed rotational frequency about the specific region;
- detecting the second laser beam by the projectile;
- ascertaining the deviation of the projectile relative to the projectile's desired course;
- and
- initiating of the trajectory correction based on the ascertained deviation.
