US12416474 - Guidance kit with variable angular offset for undetected ground suppression and methods thereof

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.

The patent describes a guidance kit for projectiles that utilizes a processor and a guidance protocol with multiple angular offset modes to accurately direct the projectile to a specified location relative to a point-of-interest (POI). It incorporates sensors like gyroscopes and accelerometers to determine the projectile’s down acceleration direction after launch, enabling precise targeting through activation of the guidance protocol.

Claim 1

A guidance kit for a projectile, comprising: at least one processor in the guidance kit; a guidance protocol operatively in communication with the guidance kit and the at least one processor and having a set of angular offset modes; at least one gyroscope operatively connected with the at least one processor; at least one accelerometer operatively connected with the at least one processor; a set of first codes provided with the guidance kit; and a first angular offset mode of the set of angular offset modes operatively in communication with the set of first codes; wherein the guidance protocol 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; at least one processor in the guidance kit; a guidance protocol operatively in communication with the guidance kit and the at least one processor and having a set of angular offset modes; at least one gyroscope operatively connected with the at least one processor; at least one accelerometer operatively connected with the at least one processor; a set of first codes provided with the guidance kit; and a first angular offset mode of the set of angular offset modes operatively in communication with the set of first codes; wherein the guidance protocol 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; wherein the at least one gyroscope and the at least one accelerometer are configured to determine a down acceleration direction of the projectile at a predetermined time subsequent to launching the projectile from a launch vehicle; and wherein the first angular offset mode is configured to activate the guidance protocol between an ON state and an OFF state.
