Abstract: An optically guided munition and control system has a replacement fuse assembly mounted on the front of a munition body or shell casing. An optical seeker subsystem detects an illuminated target and supplies signals to a processor. The processor develops steering commands sent to a flight control subsystem having a plurality of guidance canards which are actuated by drive motors through gear assemblies. The roll of the munition is established and left/right and up/down steering commands are sent to the canard drive motors based upon the optical seeker subsystem detection of the target illuminator. Range adjustment is based upon bore sight lockdown angle and cross range control is based upon left/right centering error. A code is contained in the optical radiation received from the illuminated target which must be validated by a preset code in the system processor to arm the munition.

Abstract: The systems and methods described herein allow a user to communicate using a ground sensor network that is capable of both line-of-sight (LOS) and non-line-of-sight (NLOS) communication. In particular, the systems and methods herein described transmit and receive ultraviolet radiation having a wavelength within the solar blind region from a plurality of sensing nodes arranged both in a LOS network, which communicates via LOS communication, and in a NLOS network, which communicates via NLOS communication. The ultraviolet radiation is then transmitted from the plurality of sensing nodes to a remote receiver, via LOS communication.

Abstract: A method and system for guiding and controlling an ordinance body having a trajectory and a bore sight angle including making corrections to the trajectory based on bore sight angle vs. time history. The system is incorporated with existing fuse components in a replacement kit for existing munitions. The method determines nominal time values of the ballistic trajectory of the munition in relation to launch time and determines deviation from the nominal time values by an algorithm by analyzing signals received from a source of radiation located at the target. A processor determines lateral (left/right) and range errors and provides commands to a plurality of flight control surfaces mounted on the munition.

Abstract: An optically guided mortar comprising a three axis canard assembly, an optical seeker, a guidance and control processor, and a fuze mechanism. The optical seeker is a direct replacement for existing standard mortar fuzes. The resulting system significantly improves current mortar circular error probability (CEP) and results in overall reduction of cost of target prosecution, reduction in collateral damage, improved crew survivability, and adds compatibility against limited non-stationary targets. The optical seeker detects an optical illuminator located at a target and supplies signals to the guidance and control processor which through a guidance algorithm supplies steering commands to drive motors of the three axis canard assembly which move a plurality of guidance canards to accurately direct the munition toward a target.

Abstract: The homing tag (1) has a transmissive housing (3), which is attached to a cartridge case (5). The transmissive housing (3) includes an aft body (7) to provide an interface with the cartridge case (5). Rotating bands (9) are located at a leading edge of the aft body (7). The transmissive housing (3) further includes a central body (11). The ogive-shaped nose (13) is formed of transparent material. A pluralit of slots (15) are provided for cooling the transmissive housing (3).
