E-3. Attitude Analysis Information Base Concept

Figure E-1 illustrates the information base relationship for Attitude Analysis. The information base includes a database of physical parameters, mission requirements, sensor properties, display formats, and data editing controls. In addition, the information base contains a knowledge base, which assists in the detection and diagnosis of attitude anomalies. Some code may be needed for converting tracking data to engineering units and converting between coordinate frames.

Figure E-1 also depicts the layered relationship among information base elements that can be anticipated in the SSCS application. The first layer will contain general information needed by Attitude Analysis for any mission. Subsequent layers address specific data required by each mission area, program, block, and satellite. This information-driven architecture allows a common Attitude Analysis application to support multiple satellite programs.
