Abstract: A system and method to aid in guidance, navigation and control of a guided projectile including a precision guidance munition assembly is provided. The system and method obtain raw position data during flight of the guided projectile, the raw position data including a plurality of position data points from the guiding sensor for determining positions of the guided projectile, establish a window including a portion of the plurality of position data points, smooth the portion of the plurality of position data points in the window, and determine a reduced noise position estimate of the guided projectile, based, at least in part, on the smoothed portion of the plurality of position data points in the window. The system and method may determine a velocity estimate of the guided projectile and predict an impact point of the guided projectile relative to a target.

Abstract: The system and method of attitude determination by pulse beacon and extremely low cost inertial measuring unit. A pulse beacon is used to generate a plurality of pulses detected by a detector or receiver located on the rear of a projectile such that direction of arrival can be determined. A synchronized clock proved for velocity and range information. Altitude can also be determined and may use an altimeter or the like. The use of a low cost IMU is possible with internal calibration by the system. Real-time attitude information provides for correction for crosswind and other drift enabling the system to have less down range dispersion.

Abstract: A guidance kit for a projectile and method for suppressing a point-of-interest (POI) at a desired location away from the POI. The guidance kit includes at least one processor in the guidance kit. The guidance kit also includes a guidance protocol operatively in communication with the guidance kit and the at least one processor and having a set of angular offset modes. The guidance protocol of the guidance kit is configured to guide the projectile to at least one location relative to a desired point-of-interest (POI) upon or in response to activation of at least one angular offset mode of the set of angular offset modes.

Abstract: The system and method of weapon on-board range and velocity tracking using a synchronized clock and a pulse beacon on a fire control system, or the like, coupled with an on-board rear-facing detector and processor. A round or a UAS may use this system to accurately estimate range with respect to the fire control system, over time, and the round's or UAS's velocity at various times along its flight path. The system provides for smaller miss distances, and the like.

Abstract: A system and method to aid in guidance, navigation and control of a guided projectile including a precision guidance munition assembly. The system and method receive position estimates of the guided projectile from a guiding sensor, determine predicted impact points of the guided projectile relative to a target based on the position estimates, determine miss distances of the guided projectile relative to the target, determine smoothed miss distances based, at least in part, on the determined miss distances, and process updated steering commands to steer the guided projectile based on the smoothed miss distances.

Abstract: A system and method for state estimation in spinning projectiles is provided. The state estimation is based, at least in part, on magnetic sensor data, angular velocity data, and correction terms applied to the magnetic sensor data and the angular velocity data. The system and method for state estimation in spinning projectiles estimates roll angles and roll rates of the spinning projectiles. The roll angle and roll rate estimates allow steering commands to be applied to steer the spinning projectiles in the proper direction.

Abstract: A portable launcher to launch a guided projectile at an aerial target, wherein the guided projectile has a projectile guidance kit and a target leading guidance kit that is provided with the guided projectile and the portable launcher. The target leading guidance kit includes a target lead estimation protocol stored on a computer readable media and accessible by a processor of the target leading guidance kit. When the processor executes the target lead estimation protocol, the processor is instructed to dynamically lead a reticle of an electronic sight of the target leading guidance kit from the initial target position to the lead target position in response to the projectile guidance kit detecting a speed of the aerial target and an inertial measurement unit of the target leading guidance kit that measures the slew of the guided projectile from the initial position to the translated position.

Abstract: A feed forward guidance kit for a ballistic device that includes at least one optical imaging sensor, a processor that is operatively in communication with the at least one optical imaging sensor, and a feed forward guidance protocol that is stored on a computer readable medium and that is operatively in communication with the processor. When the at least one optical imaging sensor initially intercepts an aircraft at an initial location during combat, the feed forward guidance protocol instructs the processor to proactively calculate an anticipated second position of the aircraft as an orientation of the aircraft changes from an initial orientation to a translated orientation.

Abstract: The system and method for chromatic correlation interferometry direction finding (CIDF) used to resolve ambiguities. Ambiguities are overcome by correlating over a range of frequencies. In some cases, multiple (i.e., 2 or more) frequencies or a continuous range of frequencies are used to make a more robust correlation manifold. As the complex response manifold is frequency dependent, using a set of two or more manifolds provides a significant reduction of false peaks.
