The Light Fighter Lethality Seeker Projectile (LFLSP) is a small caliber weapon with INS and imaging sensor. Its size, weight and short flight time places restrictions on guidance and control of a different dimension than normally seen in guided weapons.The initial three months of Phase I effort focussed on three areas (a) development of a 6-DOF nonlinear projectile simulation model, (b) development of inertial sensor assembly and strapdown navigation algorithms, and (c) development of simple control lawsto bring projectile close to the target. Phase I work is guided by the principle that simple INS and control laws will reduce the amount of hardware and software, and consequently, simplify the packaging problem and ultimately reduce the per round cost ofthe bullet. The overall objectives of Phase II work are to (a) perform design, test and end-to-end evaluation of navigation and control algorithms for LFLSP using a bread-board prototype system and HWIL high fidelity simulation, and (b) develop anengineering systems design for LFLSP to identify trade-offs and specify key parameters such as performance, power draw and volume. Scientific Systems Company, Inc will be supported by Draper Laboratory in all phases of the project including flight testingand commercialization in Phase III.Integration of GPS, INS, and passive imaging sensors is essential for intelligent autonomy. The proposed work has direct applications in formation flying, distributed spacecraft, telerobotics, intelligent automobiles,rendezvous and docking operations, cinematography.
