A scene correlation-based target system and related methods are provided. A reference image depicts a remotely-positioned object having identifiable characteristics, wherein a reference directional vector is established relative to the reference image. A target image of a general vicinity of the remotely-positioned object has an unknown directional vector, the target image having at least a portion of the identifiable characteristics. An inertial measuring unit has a scene correlation system, wherein the scene correlation system matches the portion of the identifiable characteristics of the target image with the identifiable characteristics of the reference image, wherein a slew angle between the reference image and the target image is calculated. A target image directional vector is derived from the calculated slew angle and the reference directional vector.

Method and apparatus for establishing a north reference for inertial measurement units using scene correlation

An optical automatic attitude measurement device for a lightweight portable optical system is disclosed. In one embodiment, a first optical device is configured to provide an attitude beam. A second optical device mechanically coupled to the first optical device to a lose tolerance. The second optical device is configured to provide a reference beam and to receive the attitude beam from the first optical device. The second optical device is further configured to obtain an attitude measurement by computing a differential measurement between the reference beam and the attitude beam in x and y planes at room temperature.

Optical automatic attitude measurement for lightweight portable optical systems

A distributed processor architecture computer system and method that includes one or more processors and object oriented control program for real time and near-real time streaming data processing which is able to change the underlying communication mechanism at runtime, which includes the use of a software interface that hides the underlying communication mechanism. The present invention permits the accommodation of changes in communication resource availability due to link, equipment, or software failures or communication bandwidth resources being used by other collaborating programs. The ability to select a communication mechanism based upon cost performance for the particular program deployment and communication mechanism availability as described in the present invention. Typical criteria used for selecting different communication mechanisms for streaming a high volume data on each individual connection would include lower latency, lower overhead time per message, higher throughput in bytes per second of a particular computer, communication equipment and operating system independence.
