Technology Marketing SummarySelf guided projectiles such as bullets that can be fired from small caliber weapons (around .50 caliber or less) are desirable due to the increased accuracy of hitting a target from a long range (about 2000 meters or more).DescriptionSandia's technology is a self-guided projectile utilizing a laser designated target and is configured to be from a small caliber smooth bore gun barrel.  The nose of the bullet is equipped with an optical sensor along with a counterbalancing mass and stabilizing stakes.  Guidance and control electronics and electromagentic actuators assist in operating the control fins and also create outputs from the optical sensors in order to steer the projectile to the target.  The current testing results have demonstrated feasibility of the design.  We are currently seeking commercial partners who may assist in further developing and deploying our design. Benefits
  • Reduced Cost
  • Aerodynamically stabilized projectile
  • Laser target designation & navigation sensor for increased accuracy
  • Experimental flight tests can be conducted using commercial off-the-shelf components
Applications and Industries
  • Military
  • Law Enforcement
  • Recreation

Small caliber guided projectile
A non-spinning projectile that is self-guided to a laser designated target and is configured to be fired from a small caliber smooth bore gun barrel has an optical sensor mounted in the nose of the projectile, a counterbalancing mass portion near the fore end of the projectile and a hollow tapered body mounted aft of the counterbalancing mass. Stabilizing strakes are mounted to and extend outward from the tapered body with control fins located at the aft end of the strakes. Guidance and control electronics and electromagnetic actuators for operating the control fins are located within the tapered body section. Output from the optical sensor is processed by the guidance and control electronics to produce command signals for the electromagnetic actuators. A guidance control algorithm incorporating non-proportional, "bang-bang" control is used to steer the projectile to the target.
