Abstract: The system and method for combining two optical assemblies into the same volume, particularly when the field of view of the two assemblies are different, so that the overall volume and size, weight and power (SWaP) for the system is reduced. This also allows both subsystems (e.g., narrow field of view (NFOV) and wide field of view (WFOV) to use a single aperture and the same external protective window, reducing overall cost for a system of co-located dissimilar optical systems in a single aperture.

Abstract: An integrated architecture and its associated sensors and processing software subsystems are defined and developed allowing a conventional unguided bullet to be transformed into a guided bullet without the use of an on-board inertial measurement unit (IMU). Some important SW components of the present disclosure include a target state estimator (TSE); a bullet state estimator (BSE); Multi-Object Tracking and Data Association; NTS GL; and a Data Link.

Abstract: Techniques are disclosed for providing information sharing with enhanced security. In an embodiment, a secure information sharing engine provides secure sharing of data by applying one or more validation rules to the data. When applied to a given portion of the data, the validation rule verifies that the data of the given portion is, in fact, the data that is supposed to be in the given portion. At least one of the validation rules includes a check that a portion of the data contained in multiple fields maintain a relationship between the multiple fields. If the data passes the applied one or more validation rules, the secure information sharing engine allows the sharing of the data. Otherwise, if the data does not pass the one or more applied validation rules, the secure information sharing engine disallows the sharing of the data.

Abstract: A system for finding up in a projectile flight relative to earth. The system having a transmitter which transmits polarized reference signals to a guidance sub-system on the projectile. The guidance sub-system includes a magnetometer and polarized and non-polarized receivers. Measurements from the magnetometer are used to determine a general up direction. The polarized and non-polarized receivers are arranged such that, during rotation of the projectile, reference signals received by the polarized receiver modulate whereas reference signals received by the non-polarized receivers are unaffected. A ratio of the strengths of the signals received by the polarized and non-polarized receivers determines alignment of a vertical axis. From the general up direction and alignment of the vertical axis, a precise up direction of the projectile in flight relative to the earth can be determined.
