Laser-guided bomb - Wikipedia, the free encyclopedia |
 | | The reflected laser light ("sparkle") from the target is then detected by the seeker head of the weapon, which sends signals to the weapon's control surfaces to guide it toward the designated point. |
 | | These weapons, such as the USAF Enhanced Paveway, use laser designation for precision attacks, but contain an inertial navigation system with GPS receiver for back-up, so that if the target illumination is lost or broken, the weapon will continue to home in on the GPS coordinates of the original target. |
 | | In the 1970s and 1980s it was common for aircraft to depend on a separate designator, either carried by ground forces, operated by the forward air controller, or carried by another aircraft in the strike group. |
