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.

A technique of managing communications among multiple modules of a munition interconnected using a computer network includes receiving, by a first module of the munition, a first set of messages from a second module of the munition. The first set of messages is received in a first protocol, the first protocol being used for communicating among the modules of the munition over the computer network. The technique further includes translating, by an interface assembly of the first module, the first set of messages in the first protocol into a second set of messages in a second protocol. The second protocol is a native protocol of the first module and is different from the first protocol. The technique still further includes providing the second set of messages from the interface module to an operational component of the first module, the operational component then responding to the second set of messages for performing a function of the munition.

The presently disclosed subject matter includes a computerized method and system for determining miss-distance between platforms. The proposed method and system make use of an electro optic sensor (e.g. camera) mounted on one of the platforms for obtaining additional data which is used for improving the accuracy of positioning data obtained from conventional positioning devices. A navigation error is calculated where the relative position of the two platforms is converted to the camera reference frame. Once the navigation error is available, it can be used to correct a measured miss-distance.

The system and method of projectile flight management using a combination of radio frequency orthogonal interferometry for the long range navigation and guidance of one or more projectiles that does not need to be accurate all the way to the ground based on the use of larger artillery. The system provides for more accurate targeting, especially in GPS-denied and GPS-limited environments.

A munition includes a munition body containing explosive material. An electronic subsystem is active between release and detonation of the explosive material. One or more batteries are electrically connected to the electronic subsystem to provide power to the electronic subsystem prior to detonation. The one or more batteries are positioned adjacent to the explosive material to be accelerated outward as corresponding munition projectiles after detonation, increasing the effective payload of the munition by performing dual functions. In one or more embodiments, the explosive material is cylindrically shaped and longitudinally aligned in a warhead section of the munition body. The one or more batteries are annularly positioned on lateral surface of the explosive surface to form a cellular fragmenting structure. In a particular embodiments, the munition body is a missile body containing a rocket propulsion system and the electronic subsystem comprises a missile guidance system.

Apparatus and associated methods relate to determining a course-correction signal for a spin-stabilized projectile based on a time sequence of images of a scene aligned with and obtained by a forward-looking imager coupled to the projectile. As the projectile rotates, the aligned scenes captured in the images obtained by the forward-looking imager are rotated. The rotation angle of each of the captured scenes corresponds to the spin angle of the projectile at the time of image exposure. Objects in the captured scenes will circle about a rotation center of the time-sequence images. The distances from a rotation center to the objects in the captured scenes, as well as the rotation angles of the captured scenes can be used to generate a course-correction signal so that the projectile can be guided to a target selected from the objects in the captured scene.
