    Abstract: A wing deployment initiator initiates penetration of frangible cover seals by missile guidance wings during wing deployment. The initiator includes a central, rotatable hub extending above a baseplate. Lobes extending from the hub prevent rotation of associated flippers by torsion springs. Locking and deployment tabs extend from the flippers into corresponding notches in proximal ends of the wings. The locking tabs prevent deployment of the wings until the central hub is rotated, whereupon the flippers are released, causing the deployment tabs to transfer deployment energy from the torsion springs to the wings. The hub can be rotated by an electrical actuator such as a solenoid or motor, or the lobes can be rotationally offset so that feedback pressure from the flippers applies a torque to the hub, and missile electronics can cause a wing control surface to inhibit and then enable hub rotation via a rocker link.

    Abstract: A system reducing pixel-based spatial noise for an uncooled infrared imager includes a first step of subtracting the historical scene-based NUC offsets for each selected pixel calculated from the previous frame. A filtered image for output module output is calculated using an edge preserving smoothing filter. The edge preserving smoothing function consists of a plus-shaped median kernel in which selected pixels that differ from the center pixel by greater than a specified threshold are replaced with the center pixel. The result is subtracted from the center pixel forming a high pass, edge ignoring, version of the frame which is dominated by system noise. A low pass version of the noise frame is created with a 5x5 mean filter. This is subtracted from the initial noise frame to improve scene rejection. This high pass version of the image / noise frame is attenuated by a configurable value.

    Abstract: An analog-to-digital converter (ADC) module includes a plurality of frequency stacked ADCs. A splitter splits channels into two segments to transmit the signal through respective low pass and high pass filters to send the analog signal to a low frequency ADC and a high frequency ADC along each channel. When using a quad-tuner having four channels, there are eight ADCs: four high frequency ADCs and four low frequency ADCs. Typically, there is one ADC associated with each channel. Thus, a quad-tuner would be used with an ADC module having four ADCs. However, by splitting and filtering each channel and increasing the number of ADCs in the ADC module, the system, assembly, and method in the present disclosure is able to increase the frequency bandwidth throughput along legacy radio frequency (RF) cables on a platform without the need of replacing any legacy hardware or the legacy RF cables.

    IPC: F42B15/01

    Abstract: The system and method of a low inertia, rolling control actuation system (CAS) for a projectile. A CAS having only two canards provides reduced cost and quicker reaction times. In some cases one or more bearings can intermittently decouple the CAS from the projectile and in some cases with the use of a brake. If there are two bearings on either side of the CAS, the front and/or back of the projectile can be decoupled to provide even quicker response times. The front of the projectile may have a warhead and additional sensors or imagers. The rear of the projectile may contain a booster or the like.

    Abstract: A guided projectile including a precision guidance munition assembly utilizes at least one maneuver envelope to optimally control movement of at least one canard to steer the guided projectile during flight. The maneuver envelopes optimize movements of the at least one canard that effectuate movement in either the range direction or the cross-range direction, or both. The maneuver envelope enables optimal timing such that maneuvering in one direction does not come at the expense of maneuver authority in the other direction.

    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.
