Highly Integrated Spinning Projectile (HISP)
Abstract
The Highly Integrated Spinning Projectile (HISP) concept minimizes the mass, complexity, and cost of an exoatmospheric homing projectile by using spin to provide an intrinsic inertial reference and target image flow to derive guidance and control. A compact electronic and/or optical computer network performs all guidance, control, inertial referencing, and target tracking functions by converting focal plane target image trajectories into divert thruster commands. Separate inertial guidance sensors are eliminated, fine thruster control is not required, focal plane quantization tolerances are relaxed, and closed loop operation permits a simple four thruster design with looser design tolerances. The trick is to develop guidance and tracking algorithms which fully utilize the minimal HISP hardware. A computer simulation of HISP dynamics and target track processing confirmed the feasibility of HISP. Recent advances in low cost electronics provide an opportunity to realistically model all essential elements of HISP in a modest hardware in the loop experiment which exploits the synergism between hardware and software simulations. Physical hardware replaces simulated projectile dynamics and target imagery, allowing realistic performance evaluation of HISP guidance and control algorithms. The long term goal is a low cost, low mass, survivable production model HISP which derives homing and control commands solely from a focal plane sensor and a modest integrated processor.
